Assignment $7$

Problem $1.$ Consider the W$10$x$33$ and W$14$x$808$ steel column sections given.

a$)$ Calculate the squash load corresponding to the maximum theoretical capacity of

each section, assume a yield strength of $50$ksi.

b$)$ Calculate the buckling load for an unbraced effective length, KL$,$ equal to $20$ times d;

normalize this in terms of the squash load calculated in a$).$

c$)$ Recalculate a$)$ and b$)$ for a solid square section having the same area as the W$10$

and W$14$ sections given. Use the unbraced effective length found in b$).$

d$)$ Recalculate a$)$ and b$)$ for a solid round section having the same area as the W$10$ and

W$14$ sections given. Use the unbraced effective length found in b$).$

For parts a$)-$ d$),$ please show your calculations but ALSO summarise your solution in

table provided

e$)$ What is observed when comparing the three cross section shapes $($W$,$ and $)?$

f$)$ What is observed when comparing square to round section shapes?

Problem $2.$ Complete Problem $7\mathrm{.}7$ in textbook $($image at right might help $?).$ You do not

need to calculate any numeric values $($the problem can be done by inspection$)$ for this

problem but may do so if you like.
