SAUDI BUILDING CODES

The first parameter concerns the Site Class according to par. 9.4.2, on the basis of which, inter alia, the Fa and Fv coefficients are determined (Table 9.4.3a & 9.4.3b). The next group of parameters concerns the selection of the mapped maximum considered earthquake spectral response S1 and Ss according to par. 9.4.1. The selection of these two parameters in combination with the soil class automatically determines the values of the Fa and Fv coefficients, which can be modified by the designer. The next parameter module concerns the selection of the Building Category according to Table 1.6-1 as well as the selection the type of construction. The choice of key shows the categories of structures according to the corresponding table in SBC 301.
