Question 1

Correct Answer:

Verified

Elastic deflection; building structures are designed to produce elastic deformation from live load.

Question 2

Correct Answer:

Verified

(i)Concrete and concrete masonry undergo moisture shrinkage only during service.
(ii)Wood- related materials (lumber, plywood, OSB, etc.)undergo moisture expansion and shrinkage during service.

Movement joints are divided into two types: (i)building joints and (ii)component joints. Building joints are further subdivided into two types. Name them.
