The time spent on human computer interaction is greatly reduced during the design process, as a results the problem on how to shorten the longperiod of structure design is largely solved.
大幅度地减少了人机交互时间，解决了高速列车流线型结构实体造型过程中设计周期过长的问题。

The seismic response of the structure with longperiod will be over estimated, if the standard spectrum or the design spectrum given by seismic risk analysis is applied.
而长周期结构采用规范设计反应谱或由地震危险性分析给出的场地设计反应谱计算所得的地震反应结果偏大。

There are many problems in traditional design method such as longperiod, structure redundancy, high cost and lack of validation etc.
