Top tie 4. Assume that the wet concrete (s.w. = 150 Ibf/ft3) behaves as a liquid. Determine the force per unit foot of length exerted on the forms. If the forms are held in place as shown, with the ties between vertical braces spaced every 2 ft, what force is exerted on the bottom tie? Brace Form 9 ft Concrete Bottom tie

Instruction: Follow Given-Required-Solution format for your computation. Complete FBD for full credit. Problem: The concrete pier is subjected to soil pressure that causes the line loads shown. Determine the resultant of the loading and find the y-coordinate of the point where the resultant crosses the y-axis.

Determine the limiting moment resisting capacity (as per LSM) of a beam cross- section having width = 250 mm and effective depth = 500 mm. The grades of concrete and reinforcing steel are M20 and Fe500 respectively. %3D
