This paper presents the results of the simulation experiment performed in Lira-SAPR. The purpose of the experiment is modal analysis of various structural schemes of the high-rise reinforced concrete frame under pulsation and earthquake action. Calculations have been made for three series of samples, differing in the stiffness ratio of the frame and diaphragm of the scheme (from 20% to 65.9%), considering seismic rating of 7, 8 and 9 magnitude and subsoils of the 1st, 2nd and 3rd categories of seismic activity. It has been established, that the ratio of stiffness influences the distribution of the modal mass. The acceleration of the cover nodes does not depend on the stiffness ratio – they grow as seismic activity of the site increases. Stiffness ratio influences the total reinforcement requirement. This influence is significant in the range of ratio values from 20.5% to 42.5%. Further increase in the stiffness ratio has little influence on the reinforcement requirement.

Anomalistic architecture especially overhanging structure has become a trend of architectural development, Based on the characteristics of a large vertical eccentric, more prominent facade and strong reverse effect,overhanging structure is often serious super-norm and extremely detrimental to the seismic design[1], Now it has become an important part of seismic review. By the analysis and comparison on the coupling of the translational and torsional seismic response from ANSYS program[2]. The behavior of seismic catastrophe of cantilever building structure is studied under bi-directional earthquake action and the change law of cantilever member with the length is obtained, the suggestions on engineering design are put forward for future seismic design of such structures.

The framed shear wall structure is a high-rise building structure with a transfer story, which has the poor seismic performance (upper rigid and lower flexible). The frame layer in the earthquake is prone to fail, which may even cause the collapse of building. In this paper, it uses the finite element software SATWE to explore the seismic performance of framed shear wall structure. Then we can draw the following conclusions: When the transfer story is set from the third layer to the ninth layer, the earthquake action of transfer story varies from 437.2kN into 564.9kN and is significantly higher than that of upper and lower layers; All the period of free vibration, angles of drift, bottom shear force, overturning moment of the structure have adverse effects on the structure, which are also detrimental to the structural seismic.

In order to analyze deformation and stress state of round link chain which it is generated by instant impact for sudden loading between the chains during the working condition, the method of symmetric penalty function was adopted to analyze contact between round link chains; and the finite element software ANSYS LS-DYNA was further used to carry on nonlinear contact analysis, the displacement curves , the stress and deformation with time were gained during the process of impact by simulating the process of the instant impact of chains. The results show that it is circular to the contact area of round link chains and it is the main reasons of damage that the greater stress and deformation of impact is caused when time lasts 0.05s through theoretical analysis and finite element analysis software. The theory equations of load conditions and the method of finite elements can provide a theoretical basis and simulation methods for analyzing the round link chain driving in a variety of different working conditions under the conditions of impact.
