Structural Fesign - Essay ExampleStructural engineers argon frankincense very important in the construction supply chain. Structural design encompasses the design of the support structure, selection of materials, computation of the member size, evaluation of the effect of the purlieu on the morphological elements, selection of the member types and lastly the configuration of the structure in the most effective, affordable, safe and serviceable manner (Heyman, 1999).The structural designer must work according to the building standardization codes. He may induct several designs of which he selects the most affective and affordable design. The design selected must not fail. To ensure proper functionality especially in the factories, the beams must not sag as this may lead to improper functioning or derailing of the cranes. Failure of the structural members results in machines drive shaft fail, machine table misalignment and burning of the bearing imputable to warbling.Simply support ed beams there ar supported vertically at two points. One point is fixed permanently plot of land at the other point, an allowance is given to enable the beam to move horizontally due to expansion (Hosford, 2005).Hollow section there are several hollow sections that are used in structural design. ... Continuous supported beams supported at several points. There are several types of beams these include Universal beams they are I shaped beams and are effective as supporting structures, they dont fail easily, they are also referred to as H section beams. Angle sections they are L shaped are mainly used for roof where struts and ties are required to make trusses.T-sections these are structural members that have a T shape.Hollow section there are several hollow sections that are used in structural design. These include extraneous hollow section that have a rectangular shape, round hollow section that have a round tubular cross-section and shape, Square sections which have a square cro ss-section and elliptical cross-section which have an ellipse shape but are hollow inside. Trusses they are mainly used for roofing there are sometimes preferred in that they may span for long distances without sagging or deflecting. There are very versatile and buttocks be redesigned easily to add more struts and ties to accommodate greater loads or span longer distances.Bars and rods bars are rectangular while rods are circular the are solid unlike the hollow section. Plates. Plates are metallic sheets with a thickness greater than 6mm. Concrete One of the most wide used structural materials. It is cheap and last long as compared to all the other materials. Concrete comprise of a mix of sand, cement and aggregate in different proportions. The strength of concrete depends on the mixing ratios. Ratios with more sand and cement have greater strength and are used in industrial constructions. Nearly all concrete mixes are reinforced with steel bars. The inherent advantages of reinforc ing concrete areThe composite structure resulting from the mix is more
