Earthquake-proof buildings are earthquake disaster mitigation priority work. Earthquake building structure may be determined, according to the design response spectrum method for determining been widely used in seismic design of buildings structures. In this paper, the structure should be designed to avoid damage in the earthquake collapsed, but the study of structural collapse behavior conducive to a better understanding of the mechanism of structural collapse and find effective anti-collapse methods. This paper was developed to simulate the complex structure collapsed procedures, through the numerical results were compared with the test, indicating that the numerical model can simulate the structural members of a variety of extreme nonlinear behavior. The structure is replaced by an equivalent single degree of freedom system corresponding to each mode and each equivalent displacement is determined using the proposed method. Thus, the seismic safety evaluation plays an important role. In recent years, with the accumulation of mature safety evaluation theory and engineering experience, the safety assessment has made great progress. Theoretical Introduction of Earthquake Response Spectrum Earthquake response spectrum can be widely applied in a single degree of freedom system, and can be decomposed into a modal method is applied to multi-degree of freedom system in seismic response. Due to post-structuralism into elastic-plastic response phase, the superposition principle no longer applies, and therefore, for most multi-degree of freedom system, application inelastic response spectra of seismic response analysis can only approximate displacement and performance evaluation structure, can’t be considered high modes of influence. Research on the structure at this stage whether it is anti-progressive collapse of the entire structure from the global focus of the system, or from the details of the start node structure, and even research has a lot of progress from the failure mechanism inside, but we can find a lot of scholars using planar framework for analysis, not a plane frame, there are many linear static analysis, nonlinear dynamic analysis in recent years increasingly popular. As the height increases, lateral structure under lateral loads increases rapidly. Tall buildings vertical loads is accumulated in the vertical component from top to bottom layer by layer transfer, which will produce large axial deformation . Therefore, the application of inelastic response spectra in engineering design is inelastic response spectra become standard design spectrum difficulties. Over half a century, many scholars have nonlinear seismic response of structures have done a lot of research, and made many useful insights. However, the current inelastic response spectra for research also can provide a major seismic design of this concept, and the relationship between the structure and the earthquake ground motion characteristics and structural dynamic parameters understanding. Tall building in central axial edge components and component deformation difference between the larger, and thus will cause a large additional moment. Tall Buildings in earthquake zones should ensure sufficient ductility to absorb and dissipate seismic energy. Therefore, in order to ensure that the structure of the plastic deformation still has good seismic performance after entering, seismic structure to take appropriate measures to ensure the structure has good ductility. International Conference on Information Sciences, Machinery, Materials and Energy (ICISMME 2015) © 2015. The authors Published by Atlantis Press 1992 Seismic Performance Targets of Engineering Designs Seismic design performance goals of buildings refer a set expected performance level of the building to earthquake ground motion. Performance level of the building includes structural, non-structural and performance of various combinations of standard construction of ancillary facilities. The current tall buildings refer the height or exceed specifications in terms of rules, procedures scope of tall buildings projects. Tall buildings structural performance targets under different levels of different earthquakes, seismic performance can be divided into the following standards : The structure has good condition and no damage after the earthquake, generally without repair we can continue to use, and people will not be due to structural damage caused by injury. Structure largely has good condition after the earthquake, only a few minor cracks in components, we generally do not need a little repair or continue to use, people will not be due to structural damage caused by injury. After the earthquake, weak parts of the structure and components of the important parts are in good condition with no damage, some other parts of the selected member has some ductility obvious cracks can be repaired and continued safe use. After the earthquake weak parts of the structure and components of the important parts have minor damage and minor cracks, some other parts of the selected member has moderate damage occurred ductility, obvious cracks into yielding stage, we need to take some safety repairs and measures in order to continue to use. Moderate structure damage occurs in the earthquake, the majority of members have minor damage, some elements have moderate damage, yielding a significant crack , we need to take security measures that people can't secure access .After repairs and proper reinforcement, we can continue to use. The structures appears significant damage in the earthquake, the majority of members have moderate damage, yielding a significant crack, some members severely are damaged, but the whole structure does not collapse, partial collapse does not occur, officers will be hurt without life-threatening. It is emphasized that the irregular structures of the ductility degree directly affect the level of deformation. This means that the seismic design tall building structure should be combined with the degree of structural irregularities, improved the structural capacity, improved ductility deformation or both of these two methods to improve the selection of reasonable and realistic processing means to ensure safety performance. In order to design the seismic performance of the proposed method overrun rise building structure design, the owners need to measure the costs required for the design, seismic examined experts determine the feasibility of a special gauge designed around the needs of structural safety and architectural design coordination . Application of Earthquake Response Spectrum With the performance of the proposed design theory, based on the performance of seismic design, the system response is equivalent to elastic-plastic systems were analyzed, and (improve) the ability spectroscopy analysis is a method, making inelastic response spectra calculations structure bomb plastic displacement of one side to the initial application. However, due to the limitations of their own, generally limited to the first mode in response to the main structure, a greater impact for the higher modes of structural response, will bring greater error; therefore, this scholar has proposed a modal method. In short, the performance of a law designed to reduce the response spectra for elastic-plastic applications provide a way out, but to make the inelastic response spectra extended to the seismic design specification there are still many difficulties . Progressive collapse is defined as the collapse of the whole building due to local weak stories or weak zones. In this paper, collapse should theoretically be avoided for any building under any earthquake, it is necessary to study the collapse behavior of buildings to acquire a better understanding of the collapse mechanism and to find efficient methods to prevent it. The collapse process highly depends on the feature of the whole structural system, so numerical simulation becomes a major method to study it. Because for the high-level framework core tube structure collapsed mainly because of damage caused compression and shear walls, steel buckling instability
