Structural design 1 - Essay ExampleFailure to assoil out proper morphologic design results to the structure being too weak and it may collapse killing many people (Charlton, 1973).A structural engineer has very important roles in designing the support of the house as well as designing the layout of the building. The engineer works closely with the house decorator to ensure stability of the building. The main challenges of any structural design atomic number 18The structure engineer has to critically evaluate and analyze different materials and their behavior when tight and select the most effective and affordable materials. These analysis are important so that the engineer can come up with a design that is scotch and can withstand load. Structural design ensures that the building stands straight, firm and safe. It also ensures that the building stand up excessive deflections that expose the structural components to fatigue. The structural cistrons must be designed to resist cracking and creep. The design postulated by the structural engineer must also take in consideration the changes in length of the building materials due to change in temperatures as this lead to deformation of materials. The design must be made to the material specifications including all the manufacturing tolerances. The major structural element used in building includes columns, beams plates, arches, shells and catenaries(Science Corporation, 2001).Columns are elements that carry the axial ... The design must be made to the material specifications including all the manufacturing tolerances. The major structural element used in building includes columns, beams plates, arches, shells and catenaries(Science Corporation, 2001).Materials and methodsIn this design the following structural members will be used. ColumnsColumns are elements that carry the axial force. The force may be either in tension or in compression. The main design consideration is the axial capacity of the column an d the buckling capacity. The buckling capacity of the element is it ability to resist buckling. This capacity dep curios on the The physical geometry of the beam The effective length of the column (this length depends on the resisting capability at both end of the column). The degree of change shape of the column determines the capacity of the column. Beams There are two types of beams used in this design. Beams are subjected to pure bending. The result of this is bending causes parts of the beam to be in tension while the other part to be in compression. Beam Sections under tension must be designed to resist it while sections in compression must be designed to resist crushing and buckling. In cases where the beams are very long, trusses are incorporated. When a beam is under tension ties are used to resist these forces, struts are used where beams need to withstand compressive forces.Cantilever beam This type of beam is supported at one end. The other end lies free.Simply supporte d beam This type of beam is supported vertically at the two ends. At one of the ends it is supported horizontally to enable it expand at its support. This prevents
