What is Earthquake Loading?

Earthquake loading comprises the forces from inertia of mass of structure. These forces are generated due to shaking of foundationof a building by seismic disturbance. The effect of translational forces from inertia of a structure is more significant than rotational or vertical component of shaking and seismic resistant design pay concentration to this force. Dynamic response of a structure against shaking of ground produces the magnitude...

How is Earthquake Loading Determined by Equivalent Lateral Force Method?

Equivalent lateral force method:  At first we will know the application and feasibility of this method, later we will know how it determines earthquake loads.  It is very simple and quick method. This method is not applicable to exceptionally high buildings having unusual structural arrangement i.e. irregular structure and tall buildings cannot be analyzed for earthquake in this method. Now question is what irregular structure is....
