A STUDY ON CALCULATION OF SEISMIC DSIGN FORCES FOR STRUCTURES CONSIDERING THEIR SEISMIC RISKS

Considering the seismic risks associated with structural damage and loss caused by various seismic forces, the total cost cannot necessarily be minimized by the verification of seismic performance using two levels of seismic forces (Levels 1 and 2 earthquake motion). Here, the total cost is defined as the summation of the initial construction cost and the seismic risk cost, which includes repair and user costs. The seismic force, with which the total cost becomes the minimum, is thought to vary with the function and type of the structure to be designed. From such a point of view, this paper presents a method for determining the target seismic design force unique to the intended structure.
