Dynamic Analysis Methods for Seismic Bridge Design Depending on the seismic zone, geometry, and importance of the bridge, the following analysis methods may be used for seismic bridge design: The single-mode method (single-mode spectral and uniform-load analysis) assumes that seismic load can be considered as an equivalent static horizontal force applied to an individual frame … Read more
Control Systems for Seismic Protection of Structures – Seminar Submitted By: Mahesh Chand Sharma Introduction Civil engineering structures located in environments where earthquakes or large wind forces are common will be subjected to serious vibrations during their lifetime. These vibrations can range from harmless to severe with the later resulting in serious structural damage and … Read more

For the convergence of solution in finite element analysis, the assumed displacement field should be isotropic . This is achieved if the components of the displacement field are complete polynomials. This is achieved by using PASCAL’s TRIANGLE. It is a technique of including the appropriate number of terms in the displacement model. It also gives … Read more
Shape functions or interpolation functions are functions used to represent behaviour of a field variable within an element. In finite element analysis we deal with different elements. The elements can be linear, quadratic, 8- noded, 9-noded etc. The shape function for these elements is required to be determined to draw a relationship between the nodal … Read more
