Abstract:In order to strengthen the understanding and the development trend of seismic design of bottom frame structure, the similarities and differences of some seismic design provisions of bottom frame structure between "78 Code", "89 Code", "01 Code" and "10 Code" were compared. From the aspects of floor number and total height limit, spacing between seismic transverse walls and seismic effect in terms of methods of bottom floor and so on, the causes of development and changes were described. And the effects on prac… Show more
