摘　　要：目的为提高超大规模工程结构地震响应分析的计算效率,提出利用云服务器开展地震响应数值模拟的方案.方法基于腾讯云等云计算环境,介绍云计算用于结构地震响应分析的可行性,并对云计算环境的搭建进行说明.利用Open Sees等软件,具体分析比较不同自由度数、不同规模的算例在云平台及本地计算环境中的计算效率.结果云平台的计算性能与本地计算环境的性能相当,可以代替本地计算环境进行地震响应分析;利用云平台并行处理计算任务,可以大大提高计算效率.结论云服务器在工程结构地震响应数值模拟中呈现出计算效率高、设置灵活、成本低的特点,具有良好的发展前景.To enhance the computational efficiency of large-scale structural seismic response analysis,the cloud server was introduced to perform the numerical simulation. Based on a commercial cloud computing platform（ e. g. Tencent Cloud）,the feasibility of applying cloud computing to structural seismic response analysis was explored,and configuration of the cloud environment illustrated. Furthermore,computational efficiencies of cloud computing and the local computing environment were benchmarked by performing a series of non-linear time-history analyses using the seismic damage simulation software Open Sees. Results showthat cloud computing has nearly the same performance as the local computing environment,but it has very significant computing efficiency,indicating that the local computing environment can be substituted by cloud computing for seismic response analyses of buildings. Conclusion is that the numerical simulation for seismic structural response based on cloud computing has high efficiency and lowcost.
