A.1.1 This part deals with the procedure for calculating the lateral forces and their distribution on structures induced by earthquake ground shaking and which shall be used in their seismic design. A.1.2 Requirements of this part are intended to preserve the integrity of structures in the inelastic range of response when subjected to earthquake ground shaking of moderate or high intensity. A.1.3 These provisions do not deal with the distribution of forces among the various components in the structures or the computation of stresses produced by these forces. A.1.4 Requirements of this part may be applied to buildings of any type, chimneys, towers, and elevated tanks. A.1.5 Calculation of lateral earthquake forces on structures in accordance with other well recognized international codes of practice is allowed, provided that the minimum seismic zone factor and ground motion representation specified in this document are considered in the analysis. A.1.6 Structures such as bridges, dams, tunnels, underground structures, domes, shell roof, and other structures not covered in section A.1.7 may require special and more sophisticated procedures for determining their design earthquake loads, and therefore, they are not covered under these provisions. However, the design of these structures shall comply with the minimum seismic zone factor and ground motion representation specified in this document.
