REVIEW ON FORM FINDING FOR DYNAMIC LOADS

Form Finding is followed by choosing the best suitable solution in terms of various design parameters having a high level of performance in terms of spaces, people, cultures and knowledge. It is process of finding the geometry in terms of load carrying capacity of a particular structure and choosing the best design in terms of its behavior against various loading conditions. It is therefore necessary to have a command over the flow of forces governing a design. The design could be made economical and environmental sustainable by using the sections which provides us minimum bending moment and shear forces. This all process involves a form to be justified and which in turn leads to form finding methods which depends on various forces, function, geometry and material. The aim is to design a structure in such a way that it should be able to sustain an impact during any structural changes or dynamic loading without losing the structural integrity. The strategy involves a good choice of design parameters which could be the shape of the structure, the location of the beams, columns and frames. Dynamic forces are those forces whose magnitude and position changes with time. The loads due to earthquake, wind and explosion activities such as blasting are categorized as dynamic loads. Due to these dynamic loads the building vibrates and gives rise to the dynamic responses. These dynamic responses are measured in terms of deformations, velocity and acceleration. A dynamic load is something that changes with time quickly as compared to structures natural frequency. Therefore, the dynamic analysis could be done manually for simple structures, but requires various techniques such as finite element method when it comes to complex engineering problems for finding various mode shapes and frequencies.
