Lesson 3 Assessment

Difficulty Level: 2/5

Estimated Time to Complete: 10 minutes

Problem Statement: Diaphragm Behaviours

A wood-frame industrial building is subjected to a net north-south unfactored wind load, as given below. All four perimeter walls act as shearwalls. The roof diaphragms are made of joists, spaced 600 mm on centre. The roof and floor diaphragms are supported by shearwalls “A” & “B” and seven glulam beams spaced 4 m O.C.

This assignment focuses on the wind load transmitted to first floor shearwalls (L1) by the floor diaphragm.

Select the most appropriate answer based on the software output and standard design requirements.

Question 1

Considering that the floor diaphragm is subjected to wind loading W (in kN) and exhibits rigid behaviour, what would be the expression of the shear force induced in shearwall "B" (in kN)? *
