A small one-story reinforced concrete building is idealized for purposes of structural analysis as a massless frame supporting a total dead load of 10 kips at the beam level. The frame is 24 ft wide & 12 ft high. Each column & the beam has a 10 in square cross-section. Assume E = 3 x 103 ksi & 5 =5 %. Determine the peak response of this frame to the El Centro ground motion. In particular, determine the peak lateral deformation at the beam level & plot the diagram of bending moments at the instant of peak response. %3D

For the data given in this problem, determine the magnitude of the active thrust on the wall retaining a c soil, using the procedure discussed in Section 16.10. Given H = 15.0 ft, c = 100 lb/ft2, = 26, = 115 lb/ft3, kv = 0, and kh = 0.3.

Two line loads q1 and q2 of infinite lengths are acting on top of an elastic medium, as shown in Figure P8.6. Find the vertical stress increase at A.

A column in a building is subjected to the following load effects: 9 kips compression from dead load 5 kips compression from roof live load 6 kips compression from snow 7 kips compression from 3 inches of rain accumulated on the roof 8 kips compression from wind a. If lead and resistance factor design is used, determine the factored load (required strength) to be used in the design of the column. Which AISC load combination controls? b. What is the required design strength of the Column? c. What is the required nominal strength of the column for a resistance factor of 0.90? d. If allowable strength design is used, determine the required load capacity (required strength) to be used in the design of the column. Which AISC load combination controls? e. What is the required nominal strength of the column for a safety factor of 1.67?

The soil profile at a site is shown Figure P16.3. Find the total horizontal normal stresses at A and B, assuming at-rest conditions.

How does a tensile stress differ from a compressive stress?
