- Abstract
- This paper deals with the history of the seismic design code, the current seismic regulations, the system of seismic design of buildings, and the seismic design of masonry structures in Mexico City. Mexico City has been severely damaged in the past by strong earthquakes. The Mexicans have a long history of the development for seismic design of buildings over fifty years. Their seismic code has been modified almost every ten years after its establishment in 1942. Some important concepts, which nowadays are commonly accepted in this field, were introduced into the earlier versions of the code: in 1942 importance factor of buildings according totheir use,in 1957 seismic force distributing along the height of buildings, dynamic analysis method, and limitation of the lateral deformation of structures, in 1966 seismic force due to the type of structures and ground conditions, in 1976 reduction of the seismic force according to plastic deformability of structures, and limitation of the distance between buildings, and in 1985 increase of the design seismic force. The current code is refined and based on the history of earthquake experiences, and development of seismic design and construction technique.
