CEE 331: Structural Analysis

Homework #5: Due October 14

Problem 1: Hibbeler 1-11. Make sure to include interior floor loads as well as roofload.

Problem 2: Consider the two way flooring system shown below. The floor slab is 6in. thick, and is made of standard stone reinforced concrete. The slab supports offices.Neglect the selfweight of the beams in your calculation. Using the tables in Hibbeler,the concept of tributary area, and elementary statics of beams:(a) compute the maximum bending moment caused by dead and live load in beam 2.Use live load reduction withKLL = 2

(b) compute the live load force in the columns. Use live load reduction withKLL = 4.

Problem 3: Consider the floor systems shown below. Make a sketch of the floor andinclude dashed lines to indicate the tributary area associated with the indicated struc-tural elements.(A) columns only.(B) beams only.

Problem 4: Hibbeler 1-16
