Simplified Models to Evaluate Site Characteristic Period

Abstract

Characteristic site period is an important index in seismic zonantion and seismic resistance design. In seismic response spectrum theory, the characteristic design period is closely related with site characteristic site period which is comprehensively covering site parameters (site categories, site shear wave velocity, site thickness, etc.). Two models, i.e., single-layer model and double-layer model, are adopted and theoretical solutions are deduced by means of the amplification coefficient function. The natural site period are theoretically deduced and presented
