Reinforcement Scheme

Coupling beam, the first line resisting earthquake, is directly related to the overall performance of the shear wall structure. Using the large general finite element analysis software ANSYS, the coupling beam span-depth ratio is 2~3 different reinforcement scheme in finite element analysis. Analysis on the ductility performance of reinforced concrete coupling beams in shear wall structure in three fields: the concrete strength grade, the longitudinal reinforcement ratio and the stirrup ratio, provides a basis for the design of the structure and to provide a reference for similar studies.

Resistance Performance

According to arrangements of local cast-in-situ regions, new precast concrete shear wall (NPC wall) has various types including integrally precast component, component with precast concealed columns and local region of wall by casting in situ, component with precast one end concealed column and the other end by casting in situ and component with all cast-in-situ concealed columns. By finite element analysis for four types of NPC wall and comparing with monolithic cast-in-situ finite element model, the lateral resistance performance of each type of NPC wall were discussed. Compared with cast-in-situ finite element model, NPC wall has rather different lateral resistant mechanism, the load-displacement curves are obviously different, and the horizontal and vertical connections decrease the strength and stiffness. The reasonable arrangement of local cast-in-situ regions can effectively improve the lateral resistance performance of NPC wall. The model composed of all cast-in-situ concealed columns, which has similar lateral resistant performance to cast-in-situ model and shows reasonable load mechanism, should be recommended. Meanwhile, the model consisting of precast concealed column and local cast-in-situ region of wall should be avoided for its poor performance.

In order to respond to the call of the strategy to vigorously carry out the fabricated structure, a new lateral connection joint-prefabricated steel joint with grouting bolt sleeve, which is adopted in the prefabricated steel reinforced concrete shear wall structure. Through uniaxial tensile test and finite element analysis, the prefabricated steel joint is comprehensive analysed, to get the impact trend of the anchorage length, sleeve wall thickness, bolt diameter to the connection performance, to determine the practicability and reliability of the connection way, and to ensure connection performance in the prefabricated steel reinforced concrete shear wall structure system. With the comparative studies, we find that, the finite element analysis and test results have high fitting degree, and can be verificated each other; the bolt diameter, sleeve wall thickness and anchor length all have positive effect trend on the tensile properties of the joint, but the influence decreases; The bolt diameter should be more than 12mm, the sleeve wall thickness should be more than 5mm, and the anchorage length should be more than 70mm; the shear bond diameter can reduce the diameter, and can change the section setting to the ring setting; the comparative results can provide reliable data support for the prefabricated steel connection joint design.

Precast Shear Wall

Aiming at the horizontal connection joint of the precast shear wall structure, this paper presents a new-type horizontal wall-to-wall connection. Based on the ABAQUS finite element analysis platform, an accurate finite element model of shear connection joints was built. By quasi-static numerical tests, the seismic behavior of the proposed connection of the precast shear wall system was analysed and compared with that of the traditional cast-in-place connection. The numerical results show that the seismic performance of the presented connection, such as deformability and energy-dissipation capacity, is slightly lower than that of its cast-in-place counterpart.

The use of finite element theory and modal analysis theory, the structure of the machine static and dynamic performance analysis and prediction using optimal design method for optimization, the new machine to improve job performance, improve processing accuracy, shorten the development cycle and enhance the competitiveness of products is very important. Selected for three-dimensional CAD modeling software-UG NX4.0 and finite element analysis software-ANSYS to set up the structure of the beam finite element model, and then post on the overall structure of the static and dynamic characteristic analysis, on the basis of optimized static and dynamic performance is more superior double wall structure of the beam. And by changing the wall thickness and the thickness of the inner wall, as well as the reinforcement plate thickness overall sensitivity analysis shows that changes in these three parameters on the dynamic characteristics of post impact. Application of topology optimization methods, determine the optimal structure of the beam ultimately.

In order to study the performance of concrete frame columns that reinforcedby assembleinclined web steel truss, with the same reciprocatinghorizontal displacement and different axialcompression.It canbe calculate the mechanical behavior of concrete frame columns and reinforced columns by using the finite element analysis software ABAQUS. Simulation analysis shows that the bearing capacity ofreinforced columnshas greatly increased andpresented a full hysteresis curve. The result shows that the reinforcement method of assemble inclined web steel truss can greatly improve the bearing capacity and ductility of the concrete frame column, and the axial compression is larger, the better the reinforcement effect.
