Some requests about the seismic design of multi - tower structure which is a kind of complicated tall buildings , are regulated in " technical specification for concrete structures of tall building " ( jgj3 - 2002 ) , but the regulations about the seismic analysis and the constructional measures are not definite and thorough enough to operate 《高层建筑混凝土结构技术规程》 ( jgj3 - 2002 )对作为复杂高层建筑结构之一的多塔结构的抗震设计做了一些规定，但对其抗震分析方法和措施未做更深入、明确的规定，可操作性不强。
And the two analysis methods are more reasonable and combinable with the actual instance than the general seismic analysis methods . this paper mainly discusses the two methods of designing actual project and offers the results of the theory and data . the pushover analysis is essentially static analysis method 静力弹塑性分析方法和时程分析方法比一般通用的振型分解反应谱抗震分析方法能够提供更合理，更符合实际的结果，本论文的讨论研究为实际工程设计中采用上述两种方法时，提供了一定的理论及数据分析结果。
Currently , researchers from home and abroad usually use simplified models in the aseismatic analyses of immersed tunnels , which can not properly simulate the two functions of the soil , while the finite element method solves this problem successfully , and the development of numeric calculation and computer technology lays a solid basis for its application , it is a pity that the applications of fem is not common currently 目前，国内外对沉管隧道进行抗震分析时，大多采用简化计算模型，将土的作用以等价弹簧和阻尼器代替，不能适当模拟土既是地震波的传播介质又是结构物的支承介质的双重作用。动力有限元法的连续介质模型很好的解决了这一问题，数值计算理论和计算机技术的发展为该方法的应用奠定了坚实的基础，然而，目前这方面的应用还很少。

After the development of nearly 20 years , the subject of damage forecasting has been extended to groups of structures from the original single ones , in another word , from one certain building to the whole city . all types of structures are involved in the job ranging the factories , facilities of lifeline , and some dangerous buildings 在近20年的发展中，震害预测已由对单体工程发展到对群体系统工程，由对某个典型工程的抗震分析发展到对一个城市或一个大型工矿企业的综合抗震能力作出全面分析判断；预测的对象涉及城市及工矿企业的各个方面，包括各类建(构)筑物、生命线工程、一些要害系统的设施及可能产生次生灾害的危险源等。
Integrated with aseismic analysis , this paper states the optimization of frame structure and minimum - cost design . tt introduces the idea and method for optimum design of aseismic structures base on optimal fortification intensity as well as how to make decision of optimal fortification intensity for aseismic structures . the sequence for optimization method is state in this paper with a example of frame calculation 本文结合抗震分析，论述了框架结构优化及构件最小造价设计。阐述了基于最优设防烈度的抗震结构优化设计的思路和方法，以及如何进行抗震结构最优设防烈度的决策。并通过框架计算实例，说明了优化的具体步骤。
Jointless bridges that use integral abutment is popular abroad ， while there are few examples of it and correlative reports at home . there are few complete analysis of dynamic characteristic and anti - seismic behavior of structure because it is a classic example of a soil - structure interaction system and the mainly unsolved problem in dynamic analysis is how to handling soil - structure interaction 目前，尚少有报道指出对具体的实桥进行过完整的动力特性分析和抗震分析，主要原因是因为整体式桥台的无伸缩缝桥梁是土体结构相互作用方面的典型例子，如何处理好土体结构相互作用是其动力分析的关键问题。
