An 18-section interactive guide to structural engineering fundamentals: cantilever retaining walls, spread footings and punching shear, drilled shafts and braced excavations, reinforced concrete columns and cantilever balconies, composite steel floor beams, roof trusses, steel connections, RC bridge pier seismic design, buried tunnel linings, curtain wall systems, the gravity load path, and a core-formula reference. Every reference drawing gets its own full-size slide so dimensions, formulas, and legends stay legible.
Chapters 1–4 cover foundations and retaining structures: cantilever retaining wall stability, spread footing punching shear, drilled shaft/caisson design, and braced excavation earth pressure. Chapters 5–9 cover reinforced concrete members: tied columns, confinement and stirrup detailing, and the full design of a cantilever balcony from rebar cage through crack control to the critical top-tension-reinforcement placement. Chapters 10–12 cover steel and timber framing: composite steel beams, Pratt roof trusses, and bolted/welded/anchor-bolt connections. Chapters 13–15 cover specialized and infrastructure structures: RC bridge pier seismic detailing, buried tunnel lining ring thrust, and curtain wall glazing design. Chapters 16–18 close with the gravity load path, a formula quick-reference, and a full fundamentals overview.

Each chapter's reference figure follows immediately after its text as its own dedicated slide, so you can view the full drawing at a readable size before moving to the next chapter.
Civil and structural engineering students building a foundation in retaining structures, reinforced concrete design, steel framing, and specialized structures; PE Civil/Structural exam candidates who want a visual reference tying formulas to real details; and practicing engineers who want a quick illustrated refresher on load paths, connection types, and code-based detailing before a design review.
The guide covers 18 chapters across five parts: foundations and retaining structures (retaining walls, footings, drilled shafts, braced excavations), reinforced concrete members (columns and cantilever balconies), steel and timber framing (composite beams, trusses, connections), specialized and infrastructure structures (bridge piers, tunnel linings, curtain walls), and a closing set of fundamentals and formula reference chapters.
A cantilever bends in the opposite sense of a simply supported span — the top fiber stretches in tension while the bottom fiber compresses. Placing the main flexural steel on the bottom face, as if the balcony were simply supported, is one of the most common and dangerous reinforced concrete detailing errors, since the slab can appear fully reinforced by bar count while carrying almost none of its actual cantilever capacity.
One-way shear is checked on a straight section a distance d from the column face across the full footing width, the same way an ordinary beam is checked. Punching (two-way) shear is checked on a perimeter located d/2 from the column face on all sides, governing a cone-shaped punch-through failure around the column — and it usually governs the design of a compact isolated footing.
Plastic-hinge zones are the regions expected to yield first and absorb inelastic rotation during a design-level earthquake. They receive much tighter transverse hoop or tie spacing than the rest of the member to confine the concrete core and delay reinforcing bar buckling, following capacity-design principles so the ductile hinge — not the foundation or a brittle shear failure — controls the structure's seismic response.
ASTM E1300 relates the design wind pressure and panel size to a required glass thickness and type, using a Glass Type Factor that reflects how much stronger a heat-treated glass type (heat-strengthened or fully tempered) is compared to baseline annealed glass, with laminated glass adding load-sharing and post-breakage retention on top of the strength calculation.
