5.5.Response of structures and codes The response of the structure to the loadings Under the dead load the building will be stressed and deflected little. When live load is added,deflection and higher stresses are produced not seriously. -The horizontal effect of wind or earthquake can be quite serious in contrast to the dead and live load situations. -The reserve load capacity supplies the additional 'margin of safety'to take care of catastrophic forces,also keep the behavior of the structure within tolerable limits of movement.5.5.
