Influence of Earthquake according to Chinese Standards

Three different Chinese standards are implemented for calculation of seismic effect for wall design which are JTJ 004-89 (Specifications of Earthquake Resistance Design for Highway Engineering), SL 203-97 (Specification for seismic design of hydraulic structures), JTS 146-2012 (Code for seismic Design of Water Transport Engineering). They are all based on Mononobe-Okabe theory. The main difference between Chinese standards and Mononobe-Okabe theory is that comprehensive influence factor Cz is introduced in Chinese standards which reduces seismic force by about 70 %.

The advantage of choosing Chinese standards as the option for earthquake analysis is that users only need to choose the intensity of the earthquake according to which the program automatically assign values of other parameters appropriate with standards.
