| Summary: | The present Aseismic Building design consept is still based on Base Shear Coefficient or Base Shear Force which is taken from a displacement, velocity or accelera tion spectrum of an Earthquake. In this thesis, a new concept is developed based on Input Energy of a structure modeled as a single degree of freedom which behave as elastic perfectly plastic. A Time Hystory Analysis of displecement, velocity, acceleration and External force of an Earthquake is first determined, and then the energy input is found from the following formula : t t t t o o o 0 M f y y dt + C f y2 dt + f F(y) y dt = f F. y dt 0 0 0 The effect of yield strength, elasticity and damping on energy input, degree of plastification, number of yield excurtion and relation of Equivalent velocity VE and maximum velocity Sv is examined |
