PSEUDO-STATIC EVALUATION OF SOIL-STEEL STRUCTURE SEISMIC BEHAVIOUR USING FINITE ELEMENT METHOD

soil -steel structures are being used with increasing frequency in recent years as highway and reilway bridges in different contries . These types of buried structures are getting more popular in iran because of variable shapes and dimensions of the structures as well as their much shorter construction period compared to traditional bridges. since the soil steel structures are usually considered as buried structures reviewing the different design codes and research works, have only shown a limited number of studies on seismic behaviour of these structures.
