Number every table and figure (Table 4.x, Figure 4.x), caption it, and refer to it by number in your text. Number displayed equations and show the substitution with units. These counts are minimums — add whatever else your design needs.
Engineering documentation standard — required in every Chapter 4 subsection
These rules are graded on every subsection. Work that misses them is capped on technical accuracy, exhibits, codes and communication, whatever the quality of the prose.
Code and standard references
- Every requirement, factor, coefficient, limit and allowable you apply cites the governing document AND the exact section, article or sub-article number — e.g. ACI 318-19 §22.5.5.1, AISC 360-22 Chapter J, Section J3.6, AASHTO LRFD 10th Ed. Article 3.6.1.2.2, ASCE 7-22 §12.8.1, ASTM D2487, state DOT manual section, local stormwater manual chapter.
- Give the edition or year of every document the first time it appears, then use a consistent short form.
- Where a code equation is used, quote the equation number (e.g. Eq. 22.5.5.1) next to your displayed equation.
- Where you depart from a code provision, state the clause you are departing from and the engineering justification.
- List every code, standard and manual actually used in a Codes and Standards table at the start of the subsection.
Citations for statements
- Every statement of fact, value taken from elsewhere, material property, soil parameter, rainfall depth, unit cost or published method carries an in-text citation (APA) to its source.
- Field and lab data cite the report, boring log, gauge, survey file or test number and its date.
- Manufacturer data cites the product literature and revision date; software results cite the program, version and model file name.
- Uncited assertions are treated as assumptions and must appear in the assumptions table with a justification.
- Every in-text citation resolves to a full entry in the reference list.
Step-by-step calculations
- Structure every calculation the same way: (1) objective, (2) governing code clause, (3) equation in symbolic form with the equation number, (4) definition of each symbol, (5) numerical substitution, (6) result with units, (7) comparison against the limit and the pass/fail statement.
- Show the substitution line — never jump from the formula to the answer.
- Number displayed equations sequentially (Eq. 4.1, 4.2, …) and refer to them by number in the text.
- State the load or flow combination governing each calculation by name.
- Carry consistent significant figures and round only at the reported result; state the rounding convention once.
- Present repetitive element checks in a calculation table with one row per element and the same column order throughout.
Free body diagrams and figures
- Draw a separate free body diagram for each isolated element — no combined sketches standing in for several members.
- Dimension every FBD: span, depth, thickness, cover, eccentricity, embedment, slope, pipe diameter, wall height — with the dimension lines and values shown.
- Label every force, pressure, reaction and moment with its symbol, magnitude and units, and show the sign convention and coordinate axes.
- Show supports and boundary conditions explicitly (pin, roller, fixed, elastic, buoyant, hydrostatic).
- Accompany each FBD with its shear, moment, thrust, pressure or hydraulic grade diagram at the same scale reference.
- Number and caption every figure (Figure 4.x) and refer to it by number in the narrative; add a scale or north arrow to plans.
Units and notation
- Every number in text, tables, figures and equations carries its unit — no bare numbers.
- Use one unit system throughout (US customary or SI); if both appear, give the converted value in parentheses consistently.
- Check dimensional homogeneity of each equation and say so — the units of both sides must match.
- Provide a nomenclature table defining every symbol with its unit.
Checking and verification
- Every calculation is checked by an independent route — hand check against software, alternative method, order-of-magnitude estimate, or a published worked example — and the check is shown, not just claimed.
- Report demand-to-capacity ratios and factors of safety against the required values, with the source clause for each required value.
- Include a verification/checking table: item, method of check, expected, obtained, difference, accept or revise.
- Sanity-check every result (magnitude, direction, plausibility) and state the conclusion.
- Record who checked the work and on what date; flag anything still unverified as an open item.
- State limitations and the range over which the result is valid.

Masonry Design

Section B
Engineering story
A real project situation that frames this module
It is week 5 of implementation and the structural engineering team has reached masonry design. Designs reinforced masonry walls and piers for out-of-plane and in-plane loading per TMS 402/602. The plan reviewer at the building department asks one question: what establishes that allowable stress design (ASD) and strength design (SD) methods for masonry?
The team treats out-of-plane flexural design of reinforced CMU walls as a background assumption instead of an input that must be established and recorded. The result is an element loaded beyond its governing limit state, discovered only after the design of record that drawings, quantities and cost are generated from has already been built on it.
Building occupants, erection crews and the structural engineer of record carry the consequence. On this module specifically, the exposure runs through in-plane shear wall design and reinforcement detailing, and the cost of correction rises every week the calculation package and framing drawings moves closer to issue.
Decisions the engineer must make
- What record establishes allowable stress design (ASD) and strength design (SD) methods for masonry, and is that record in the project data inventory?
- Does TMS 402/602-22 (2022), Ch. 9, govern here — and is that the edition adopted by the jurisdiction?
- What is the acceptance criterion for out-of-plane flexural design of reinforced CMU walls, and was it written before the result was known?
- Is Mn = As·fy·(d − a/2) valid over the parameter range this project actually occupies?
- If the check fails, does the team revise the calculation package and framing drawings or raise a change request against the locked baseline?

Section C
Why this matters
Professional
A licensed engineer defending masonry design cites TMS 402/602-22 (2022), Ch. 9, and shows the record behind each input. Your masonry wall design calculation set with reinforcement spacing detail. is reviewed the same way — traceability is assessed before arithmetic.
Technical
Allowable stress design (ASD) and strength design (SD) methods for masonry is what makes Mn = As·fy·(d − a/2) usable on this project rather than a formula copied from a reference. Get it wrong and every quantity derived from it is wrong by the same factor.
Safety
The failure mode this module guards against is an element loaded beyond its governing limit state. It reaches people through grouting, cell reinforcement spacing, and prism strength f'm, which is why the safety check is recorded explicitly here rather than inferred from a passing strength or performance check.
Economic
The design of record that drawings, quantities and cost are generated from is priced from this work. Quantities, unit costs and schedule float all trace to allowable stress design (ASD) and strength design (SD) methods for masonry; a late correction here is paid for as a change order, not a redline.
Environmental
Environmentally, this module fixes embodied carbon in concrete and steel, and the demolition waste of a redesign. Choosing conservatively without justification is not free — the excess shows up as material, energy and land that the project consumes for no measurable gain.
Community
Occupants who rely on the structure performing through its design life and design event inherit whatever this module decides — performance, accessibility, cost of ownership and resilience are set here, not at the ribbon-cutting.
Section D

The engineering content of masonry design
Designs reinforced masonry walls and piers for out-of-plane and in-plane loading per TMS 402/602. That single sentence hides the substance of the module: allowable stress design (ASD) and strength design (SD) methods for masonry, and out-of-plane flexural design of reinforced CMU walls. Both must be established from project evidence before anything downstream is credible.
In structural engineering, this work is the input to the calculation package and framing drawings. In-plane shear wall design and reinforcement detailing — which is why this page asks you to record the source of every quantity, not just its value. The design of record that drawings, quantities and cost are generated from depends on it.
- Allowable stress design (ASD) and strength design (SD) methods for masonry
- Out-of-plane flexural design of reinforced CMU walls
- In-plane shear wall design and reinforcement detailing
- Slenderness and P-delta effects in masonry walls
- Grouting, cell reinforcement spacing, and prism strength f'm

Governing relationships and how they are applied here
The relationships below govern masonry design. Mn = As·fy·(d − a/2) — each is valid only inside the parameter range this project occupies, so state that range before substituting.
Out-of-plane flexural design of reinforced CMU walls sets the values you place into these expressions. Any code-prescribed factor must match TMS 402/602-22 (2022); a factor lifted from a different edition silently changes the answer.

Constraints, adopted standards and the safety case for masonry design
TMS 402/602-22 (2022), Ch. 9, governs this module: Strength design of reinforced masonry members
The safety case is explicit here. The failure mode is an element loaded beyond its governing limit state; the people exposed are building occupants, erection crews and the structural engineer of record; the control that prevents it is grouting, cell reinforcement spacing, and prism strength f'm together with an independent check by someone who did not perform the work.
- Controlling criterion for this module: allowable stress design (ASD) and strength design (SD) methods for masonry.
- Adopted reference: TMS 402/602-22 (2022) — cite Ch. 9 by number.
- Failure mode guarded: an element loaded beyond its governing limit state.

Where this method stops being valid
Every method has a domain of validity. State the range of geometry, loading, material behaviour or flow regime over which your approach holds, and state what you would do instead beyond it.
For this project, the boundary you are most likely to push is grouting, cell reinforcement spacing, and prism strength f'm. If you cross it, say so in writing, bound the error, and carry the limitation into your results chapter. A disclosed limitation is professional practice; a silent extrapolation is not.

Common mistakes and how to avoid them
- Treating allowable stress design (ASD) and strength design (SD) methods for masonry as a given instead of establishing it from a project record.
- Producing masonry wall design calculation set with reinforcement spacing detail. without showing how out-of-plane flexural design of reinforced CMU walls was satisfied.
- Substituting into Mn = As·fy·(d − a/2) outside the range where it is valid, and reporting the number anyway.
- Missing grouting, cell reinforcement spacing, and prism strength f'm, which is exactly the path to an element loaded beyond its governing limit state.
- Designing to the average condition when the governing condition is the controlling one.
- Freezing a design before the constructability and access review that would have changed it.
- Reporting numbers without units, or mixing US customary and SI inside a single calculation chain.
- Citing the wrong edition of a standard, or citing a standard that does not govern the jurisdiction.
- Leaving boundary conditions undefined so the model is not reproducible by an independent checker.
