The Analysis Of Seismic Performance Of HPC Shear Wall Structure With Double Beam

From the previous earthquake disaster,We can see that shear wall structure showed good seismic performance;The development of urbanization and increasingly scarce land resources,All this promote the development of high-level structure. Shear wall structure is one of the main structure of High-level structure,developed rapidly in recent years. But shear wall structure has a major shortcoming,That is its damage is marked by the destruction of the wall for, It is difficult to repair the damaged wall for. The greater stiffness of the wall for the worse its ductility,So it is worth for us to explore how to improve the ductility of structural form,and how to repair the damaged structure easily.As the high-performance concrete is hot in this century,and there are more research about its application,Therefore, this article will first consider the perspective of high performance concrete, Describes the characteristics of high performance concrete, preparation requirements, development and application of the understanding of their development situation. Then affect the seismic performance of shear walls and beams to the wall for consideration, analyzes the role of these two mechanisms, failure modes, and other factors. Finally, combining these three parts of a high-performance concrete shear wall structure of two-beams case analysis to compare the double wall structure with ordinary shear beam structure of the force performance, added even more size on the beam cross section the double wall beam structure.The results show that, whether or not considered with the beam stiffness increases, compared with the normal wall structure, double wall structure of the shock beam cycle has increased in type raise the rate then increases with increase in beam section size large decrease; double beam structure has changed the maximum story displacement, reaction force, velocity, acceleration, the maximum story drift hazardous location and size, so that the distribution of plastic hinges greatly changed, changed the weak layer Location, with emphasis on the first floor beam with added control and position choice.
