PKPM and SAP2000 software on a layer of engineering aseismic structure performance analysis based on structure mechanics Jia Le Zhao1,a，Zheng Zhen2,b 1,2 Department of Civil Engineering, Taiyuan University of Technology #79,YingZe West Street, Taiyuan, 030024, China azjl_3023456@163.com, bzhenzhengtyut@163.com, Key Words: structural design; modeling principle; application program; vibration mode analysis Abstract: The paper respectively introduced the principle of PKPM and SAP2000 application of modeling, At the same time, these two kinds of software are based on structure mechanics. practical engineering projections of these two applications, and engineering seismic performance analysis to compare their conclusions with some guiding significance for understanding the PKPM and SAP2000 application of, and provide a reference for personnel engaged in structural design.
Engineering seismic design is the key to ensure the quality of the engineering seismic fortification.
Therefore, SAP2000 is especially applicable to structure dynamic analysis in civil engineering.
The same as other large finite element program SAP2000 geometry physical model is consists of two aspects: The first aspect is, made up of "node - unit - structure" geometric model; The second aspect is made up of "materials - section – units " the physical model.
SAP2000 offers a variety of common material attributes of the building structure, materials such as concrete, steel, aluminum, etc., and it can also customize corresponding material properties, according to user s ' need; SAP2000 also provide many kinds of section form, such as frame cross section and surface cross section, etc.

Cost controlling is key behavior of getting more profits in an enterprise, but the cost of construction material cover 40-60 percent or more.
Especially for those bulk materials, such as steels, etc.
Before purchasing materials, prices should be balanced, if the price will be high, purchasing more maybe is not reasonable, because, storage of construction materials will spend certain money, if we don’t store correctly, materials will be waste.
At the same time, source staff should have rich knowledge and capacity in engineering, cost, law, negotiation and signing of contracts.
Summary Because of the position of material cost in construction engineering, the affection of controlling of procurement cost of construction material is tremendous.

In the light of the excellent performance of various energy dissipation devices in area of mechanical engineering, kinds of dampers had been produced and installed in engineering structure for energy dissipation.
The use of Tuned Liquid Dampers (TLD) to minimize the structural vibration in civil engineering was started from the mid 1980's [6], whose emergence and successful application in engineering structure has already inspired the enthusiasm of many scholars to research.
Key issues of the performance-based design for passive energy dissipation system.
With more and more new technologies and materials are constantly emerging, more dampers with higher performance are to be researched and developed.

Research and application of geopolymer cementitious material progress and review Ou Zhongwen1, a, Zhou Shangyong2,Xu Chunxia1, b, Zhang Yi2, Yang Jinchao1, Li Yuexia1 1 Chemical and Materials Engineering Department, Logistic Engineering University of PLA, Chongqing 401331, China; 2 Chongqing Construction Residential Engineering Co.
The cementitious material is of the key, the highest price, pollution load of material.
With further research and developments of preparation technology recently, the geopolymer cementitious materials have been applied in the following fields: （1）Construction engineering field.
The United States, Germany and other countries have used polymer cementitious materials in building engineering with high requirements on strength, fire resistance, high durability.
Shanghai Jiantong Engineering and Construction Co. utilizes goepolymer cementitious materials as grouting material in application to improve subgrade strength.

Scaling-up and three dimensional (3-D) near-net shape forming technique for FGMs are one of the most important key-factor to produce the industrial engineering components and products in practical use.
The ability of the SPS process to apply a wide variety of materials in applications varying from structural materials to functional materials provides a versatility and high productivity with enormous potentiality for cost effectiveness and widespread use in a practical product area [1,2].
