求翻译：As explained earlier in Section 2, according to AASHTO article 4.7.4.2, single-span bridges require no seismic analysis and only the connection of the superstructure to substructure is designed for an acceleration of S×A, where A is the peak ground acceleration for the seismic zone and S is the site coefficient. Althou是什么意思？

正如我刚才解释在第2，根据AASHTO第4.7.4.2，单跨桥梁不需要抗震分析和设计的加速只子上层建筑的连接×，一个是地面峰值加速度为地震带和S是网站系数。虽然反应谱分析通常不要求
