Composite Construction

Composite construction is the construction of structures in which two or more materials are used. Regarding structural engineering, composite construction is a construction where two materials are bound together in a technical manner such that both the materials act as a single unit to carry and transfer the load. The motives of composite construction are to increase the structural strength, make structures more aesthetic, and provide a sustainable environment.

Give full explanation Awall form 14 ft high is filled with 160 lb per cu ft concrete at a tem perature of 70°F. The concrete is Type I without a retarder. Concrete will be placed with normal internal vibration to a depth of less than 4 ft. The rate of placement is 5 ft per hr. From Table 1, the value of Cw is 1.1 and from Table 2 the value of Cc is 1.0. The rate of placement is less than 7 ft per hr and the place ment height does not exceed 14 ft so calculate the lateral pressure by using appropriate formula.
