Behavior of Structural System
What is the centroid (y bar) of the shape?
What is the moment of inertia (Ix) of the shape?
(If y bar is 13.37cm)
Calculate and draw the shear and moment diagram for the beam shown.
Design a 4” wide wood beam for the shear demand of 4312lbs.
(Fv=180psi; Table pg.476 book)
Design a 4” wide wood beam for the moment demand of 11,146 lb-ft.
(Fb=1500psi; Table pg.476 book)
For the column footing shown what is the actual bearing pressure (qs) and the factored Bearing pressure (qu)?
Is a 1 foot thick footing adequate for two-way shear if the qu=4 k/ft^2?
(f’c=4000psi)
What is the As required for the footing if qu=4 k/ft^2?
(f’c=4000psi)
What is the buckling load for a A50 W16x40 column with the both ends fixed and the y-axis braced at mid-height?
What is the crushing load for a A50 W16x40 column with the both ends fixed and the y-axis braced at mid-height?
