FOUNDATION is the lowest supporting layer of a structure. * Purpose: Transfer the building load to the soil. * The size of the foundation is determined by the weight of the building and the load bearing capabilities of the soil. * When the load bearing capabilities of the soil is low‚ a footing is usually used. Types of Foundation 1. Shallows Foundations * Shallow foundations are those founded near to the finished ground surface; generally where the founding depth (Df) is less than

The principal structural elements of a typical multi-storey building comprise floors‚ beams and columns. A wide variety of alternative forms and arrangements can be used in multi-storey steel framed structures.

after the bridge collapsed‚ we realized that one of the connectors was loose and it broke into two. If we were to build this bridge again‚ we would check all of the connectors to make sure they are new and secure. Whose bridge had the highest structural efficiency? Why do you

i) Frictional Unemployment The function of labour market is to match available jobs with available workers. If all jobs and workers were the same‚ or if the set of jobs and workers were static and unchanging‚ this matching process would be quick and easy. But the real world is more complicated. In practice‚ both jobs and workers are highly heterogeneous (non-uniform). Jobs differ in their locations‚ in the skills they require‚ in the working conditions and hours‚ and in many other ways. Workers

Most structural steel failures happen at connections....where a beam connects to a column‚ where a joist connects to a beam‚ where a hanging rod connects to a beam (the Kansas City Hyatt discussed above). The Structural Engineer must design the design the steel members and give guidelines for the connections. Many people in the Construction Industry don’t understand‚ though‚ that the Structural Engineer rarely designs the connections. Why is that? Historically‚ the Steel Fabricators developed

strong‚ suspension bridges can span distances from 2‚000 to 7‚000 feet far longer than any other kind of bridge. Suspension bridges tend to be the most expensive to build. Many bridges in the past have had structural failure. One of the two major contributors to flaw is the weather and structural design. For example the Tacoma Narrows Bridge was the third longest in the world in 1940. The bridge would move from side to side in the wind‚ but after 4 months it was built the bridge collapsed in 42 mph

TENT STRUCTURES Definition of a Tent Structure: A membrane structure pre-stressed by externally applied forces so that it is held completely taut under all anticipated load conditions. To avoid extremely high tensile forces‚ a membrane structure should have relatively sharp curvatures in opposite direction (Reference: The Visual Dictionary of Architecture‚ Ching). Purpose: The purpose of a tent structure is to provide a means of shelter that is lightweight‚ portable‚

called a consensus theory. Marxism and functionalism are similar in that they see that the way society is structured as an important part in determining the way people have relationships and behave between themselves. This is known as structural perspective. Both functionalists and Marxists believe that people are portrayed as creature within the social system. Functionalists believe that society operates to the benefit of everybody. They stress that societies continue to exist

Heavy construction equipment was located on the one of the weakest points in the structure. | URS did not evaluate fatigue of structural members and did not analyze the redundancy issues related to the structure. URS did not put warning sighs related to the bridge structure. Nobody noticed the inadequate gusset plates during an inspection or while recalculating loads for planned
