| Abstract: | The second bridge crossing the Panama Canal is a cable-stayed bridge with a main span of 420 m.Because of the bridge's long main span and the potential for strong seismic activity in the area,several different design codes were used in developing the design criteria for the bridge,all of which are introduced in this article.Besides,This essay also introduces a thorough analysis of the seismic hazards at this site,and the investigation and design of the main tower configuration,the cable configuration,the span layout and the superstructure cross section as well. |
