efer to the simply supported beam from Problem $1.(20$ Marks$)$

a$)$ Assume that the beam supports architectural elements that are likely to be damaged due

to large deflections. The architectural elements were installed right after the application of

dead loads. Are the beam deflections within the limits prescribed by CSA A$23\mathrm{.}3?$

b$)$ Suppose that the architectural elements described in part a$)$ are installed $1$ year after the

construction. Find the maximum long$-$term deflection for this beam $5$ years after the

architectural elements have been installed.

c$)$ Comment on the effect of the installation schedule for architectural components on the

magnitude of long$-$term deflections
