Abstract: In the current code of seismic design in our country,infilled wall are considered as non-structural component and do not participate in the seismic checking. In the bottom frame structure, the infilled wall of the first floor often change the number and position for using function at random,this will have unfavorable impact on the main structure. In this paper, a serious damaged bottom frame structure in high intensity area in Wenchuan earthquake is taken as the research object,and 3 comparative calculation models are designed, elasto-plastic time-history analysis is carried out on the use of ABAQUS finite element software. The calculation results show that: the first layer containing infilled with high wall content ratio will reduce the first floor damage, but causing the weak layer of the overall structure transfer from the bottom to transitional masonry story which aggravates damage, at the same time, an appropriate increase in wall content ratio can reduce the torsional response at a certain extent; nonuniform arrangement infilled wall has little effect on the floor deformation and resistance, but it will increase the torsional response of the whole structure.

Abstract: On the basis of structural concept design, this paper puts forward a new braced controlled rocking reinforced concrete frame structure system, researching dynamic characteristics of the BCR-RCF structure when the joints is been weakened in different levels by using finite element analysis software Abaqus, analyzing the reasonable degree of rocking joints stiffness weakening. By comparing the dynamic response of conventional reinforced concrete frame and the BCR-RCF structure, it shows that the BCR-RCF structure can effectively reduce the structural shearing force and acceleration response, however, displacement and velocity response is bigger than RCF structure. Compared with the RCF structure, shearing force and displacement responses of the BCR-RCF are more evenly distributed along the floor, which helps preventing excessive concentration of interlaminar deformation, so that materials of every layer can be fully utilized. After adding metal damper into the BCR-RCF structure, the displacement response can be effectively controlled.

Abstract: The mechanics analysis of integral building structure needs the accurate ABAQUS finite element analysis, but due to the ABAQUS function limits the building structure modeling is a great workload and how to model an integral structure more quickly and efficiently become a difficult problem. In order to reduce the workloads in the ABAQUS analysis, the new ABAQUS standard layer assembly modeling approach was proposed. Firstly, according to the data structure of the ABAQUS software’s INP file, the program computational algorithm was proposed. And by a Python self-written program, the example engineering structure model was completed using this standard layer assembly approach. The usage of this new ABAQUS modeling approach makes the modeling more easy and efficient. After that, by comparing the ABAQUS standard layer assembly model calculation results with the results calculated by another finite element software, it is clearly illustrated that the ABAQUS standard layer assembly modeling is more accurate and can be applied in the structure analysis.

Abstract: The single UHV electrical equipment and numerical model for its circuit would be established by the Ansys software, after respectively analyze the Earthquake acceleration response spectrum of all the models, the stress distribution of equipments of all numerical model and its top displacement results would be get. By comparing the differences of every model’s result and focusing on the load-carrying properties of the structure, the experiments would get further optimizing space and confirm the circuit connection mode that is favorable for the Seismic resistance. After the comparison of single equipment and circuit results, it is suggested to establish a complete circuit numerical model while analyze and verify the converting station.

Abstract: This paper is aimed to research on bending of shearing strength about the three different kinds of GFRP connectors, determining shearing mechanical properties of GFRP connectors, and providing the reference so as to apply in engineering practice as soon as possible. By designing for a total of six groups of three specimens were loaded in accordance with the method of Static Load on my own,then three groups of connectors cracking displacement and ultimate displacement were compared ,so as to arrive three different kinds of shearing mechanical properties of GFRP connectors.According to the test data,these three kinds of connectors cracking displacement and ultimate displacement of V (45°)-type connected specimens are minimum, U-type connected specimens are maximum. Receive the displacement control of V (45°)-type connected specimens of the three works best,shear capacity is relatively good.

Abstract: This paper puts a form of reinforcement with used finite element methods to carry on the numerical simulation of a new type reinforcement form of light steel ceiling. Compared with the ordinary ceiling, the new reinforcement form of light steel ceiling can greatly improve the capacity of the ceiling sideways resistance with the overall strong stiffness from the simulation results.

Abstract: Purlin connections have important influence on the stiffness, bearing capacity and the purlin calculation methods. A new kind of purlin connection was put forward in this paper. The mechanical behavior of the new connection was studied by finite element analysis using software ANSYS. As can be seen from the simulation results, the new connection can enhance the stiffness of purlin, and effect of each new wave connection is better than the promotion of purlin stiffness in the vibration wave connection. New connection has a better promotion effect for small stiffness of purlin.

Abstract: Steel silos lack of systematic theoretical research. Based on a large floor-ash steel silo, for example, in view of a large number of documents based on the relevant specifications, the temperature load of steel silo effect is analyzed. The results show that: for those steel silos which are constructed in a larger temperature difference between regions, warehouse wall stress induced by the temperature load can not be ignored; at the bottom of the storehouse, the hoop stress, vertical stress load vary linearly with temperature, therefore, when the temperature difference is large, the temperature stress at the bottom of the warehouse is much larger than the warehouse wall stress induced by the storing load; the temperature stress at the bottom of the steel silos changes in shape of a parabola according to the silo diameter and the warehouse wall thickness. Therefore, in a certain range, reducing the diameter of the silo but increasing the thickness of the steel silo warehouse is harmful to the steel cylinder.
