Question
Determine: - required cable diameter in mm - axial load in each tower in kN - bending moment at the base of the tower - required volume of the concrete anchor blocks in m³
SITUATION. The cable of a suspension bridge shown in the figure below runs over a frictionless pulley on the top of each of the towers at A and B and is fixed to anchor blocks at D and E. The cable carries a uniform horizontally distributed load of w = 160 kN/m. The permissible working stress of the gross area of the cable, including voids, is 800 MPa. Unit weight of concrete is 23.4 kN/m³. For this problem, L=400m, S=40m, H=60m, a=45° A S W(kN/m) H Anchor Anchor
