Question
An L= 27-ft-long soldier beam is used as a key component of an earth retention system at an excavation site.
The soldier beam is subjected to a soil loading that is linearly distributed from WA = 590 lb/ft to WC = 210 lb/ft, as
shown. The soldier beam can be idealized as a cantilever with a fixed support at A. Added support is supplied by
a tieback anchor at B, which exerts a force of P = 4100 Ib on the soldier beam at a = 21 ft. Determine the horizontal deflection of the soldier beam at point C. Assume El = 4.9 × 10^8 Ib-in.^2. Deflection is positive to the
left.
