- A planned flexible load area (see Figure P7.2) is to be 3 m × 4.6 m and carries a uniformly distributed load of 180 kN/m2. Estimate the elastic settlement below the center of the loaded area. Assume that Df = 2 m and H = . Use Eq. (7.4).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 = 460 lb/ft to wC = 200 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 = 4000 lb on the soldier beam at a = 21 ft. Determine the horizontal deflection of the soldier beam at point C. Assume EI = 6.9 × 108 lb·in.2. Deflection is positive to the left.A 5-m propped beam carries a uniformly distributed load equal to 45 kN/m applied throughout the beam. If the reaction at the roller is 84.375 kN, what is the maximum flexural shear stress if the beam has a rectangular cross-section with b = 300 mm and h = 600 mm? (in MPa)
- Question 3 5 pts What is the larger vertical reaction of a 6- m simply-supported beam carryinga triangular load which varies from 0 at one support and 15 kN/m at the other support? (Answer must be in kN.)A raft of size 4 m-square carries a load of 400 kN/m2. Determine the vertical stress incrementat a point 5 m below the centre of the loaded area using Boussinesq’s theory. Compare theresult with that obtained by the equivalent point load method and with that obtained bydividing the area into four equal parts the load from each of which is assumed to act throughits centreThe lower ends of the three steel rods are at the samelevel before the force P = 600 kN is applied to thehorizontal rigid slab. For each rod, A = 2000 mm2 α = 11 .7 μm/m0 C, and E = 200 Gpa. Determine therelationship between the force in rod C and the changein temperature ∆. Neglect mass of the slab.

Concrete weighs 23.6 KN/m^3. Fibd the 1. Total vertical reaction at the bottom of the dam 2. The factor of safety against sliding if the coefficient of friction at base is 0.70 3.the factor of safety against overturning 4. The soil pressure at the heel and atvthe toeA 5-m simply-supported beam supports a uniformly distributed load equal to 40 kN/m applied throughout the beam. What is the maximum flexural stress if the beam has a triangular cross-section with b = 300 mm and h = 600 mm? (in MPa)An L = 23-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 = 410 lb/ft to wC = 290 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 = 4500 lb on the soldier beam at a = 18 ft.
