ARCH 4 Overview - Examples & Applications

These overview examples establish the review discipline used throughout ARCH 4 before students enter the timber- and steel-specific modules.

Example 1 — Identify a consistent design basis

A steel member problem gives service dead and live loads but also provides LRFD resistance factors. What must be established before comparing demand with capacity?

Example 4 — Separate strength and serviceability

A beam passes its bending-strength check but exceeds the selected project deflection criterion. Is the design review complete?

Example 5 — Do not approve a connection from bolt count alone

A connection carries 300 kN and a preliminary calculation assigns 75 kN to each of four bolts. Does that establish connection adequacy?
