Painting and sculpture gallery - Essay Example The extent of the material elasticity greatly determines its stability under such a load. Continuous increase in the load applied to a structural element lead to an increased deformation. There is a limit reached where the material loses it elastic nature. This limit is refereed to as the elastic limit. Further stretching of the structural member beyond this limit results to permanent deformation of the material. Beyond the point of elasticity, hooks law ceases to apply, the material behaves in a plastic manner, plastic material do not return to their original shape after the load has been removed. At yield point the material may collapse. It is upon the structural engineer to perform comprehensive calculation of the loads applied to a building and come up with a suitable structure to resist the calculated load. There are two types of loads. There is the live and dead load. Structural elements are also subjected to compressive loads. This causes a decrease in the original size of these elements and a consequent increase in the cross-sectional area of the element. A compressive force in a building affects structural elements such as columns, struts and beams. Excessive compressive forces results to the buckling of these structural materials. The designer must calculate these compressive load and select materials that can withstand buckling.Creep is another structural effect that affects materials used in building and construction; udder creep the material is slowly and progressively deformed. This mainly occurs when structural members are subjected to high temperatures, continuous vibration from heavy machines and repeated cyclic stress. Creep leads to the gradual sagging of ties and beams and the loosening of bolts use... Tension, which is the degree of material deformation due to the material being subjected to a pulling force results changes in shape of the ties that are used during the construction of trusses, the tension should be accurately calculated to ensure that the deformation on the structural members does not exceed the yield point.Structural elements are subjected to compressive loads.

Creep is another structural effect that affects materials used in building and construction; udder creep the material is slowly and progressively deformed. This mainly occurs when structural members a re subjected to high temperatures, continuous vibration from heavy machines and repeated cyclic stress. Creep leads to the gradual sagging of ties and beams and the loosening of bolts use to join the structural elements. The designer has therefore to take into account such unnoticeable changes that may lead to rapture of the material. Creep lead to material fracture. The progressive fracture of material leads to fatigue and finally the material fails.
