Frame shear wall structure as a high-rise building one of the most widely used structure form, has good seismic performance and high bearing capacity, the frame shear wall structure research focused on the study of shear wall quantity more, pay attention to consider shear wall quantity and the intrinsic relationships between shear wall lateral stiffness and to seek the optimal design of shear wall stiffness, ignores the position of the shear wall, on the whole architecture of the influence of lateral stiffness, and can go, is set the location of the shear wall is difficult to study, this article will focus on the research of location of shear wall structure seismic performance, provide reference for the future of this kind of structure design.

Mechanics Characteristics

The high-rise concrete residential market has been a gradually urban mainstream in recent years, and frame-shear wall structure is more used for high-rise residential structures now. This kind of structure has the advantage that the combination of frame and shear wall make the space free and flexible, and therefore the whole structure has considerable rigidity. The structure can not only satisfy the needs for people living in comfortable, but also has good dynamic and static load bearing capacity. This paper analyzed the mechanics characteristics of the structure and summarized the two kinds of main failure modes of shear wall and frame structure in earthquake. On this basis, the main principles are put forward to improve the seismic behavior of the shear wall. And further some of specific measures and suggestions which can improve the seismic performance for the frame-shear structure are introduced.

Collapse Process

AbstractOn June 24, 2021, a 40-year-old reinforced concrete flat plate structure building in Miami suffered a sudden partial collapse. This study analyzed the overall performance and key components of the collapsed building based on the building design codes (ACI-318 and GB 50010). Punching shear and post-punching performances of typical slab-column joints are also studied through the refined finite element analysis. The collapse process was simulated and visualized using a physics engine. By way of these analyses, weak design points of the collapsed building are highlighted. The differences between the reinforcement detailing of the collapsed building and the requirements of the current Chinese code are discussed, together with a comparison of the punching shear and post-punching performances. The simulated collapse procedure and debris distribution are compared with the actual collapse scenes.

Abstract: Current styles in the construction industry demand tall and light buildings, which are also flexible and low-cost. This increases the chances of failure and problems from the point of view of usability. Many modern methods are available to reduce structural vibration, with many vibration control strategies, the idea of using the new TMD. This study was conducted to study the efficacy of using TMD in controlling structural movement. Initially a numerical algorithm was developed to investigate the response of a shear structure containing TMD. Next another numerical algorithm was developed to investigate the response of an independent 2D model programmed with TMD. Three slow loading methods used. The first was a sinusoidal upload, the second was in line with the corresponding timeline according to IS-1894 (Part -1): 2002 with 5% erosion (PGA = 1g) and the third was 1940 El Centro Earthquake Record (PGA) = 0.313g). From research it has been found that TMD can be used effectively to control building vibrations. TMD worked best when the softness of the structure was low. Gradually increase the magnitude of the effects of TMD on the gradual decline in the response to structural migration.

Under the rapidly advancing economic trends, people’s requirements for the functionality and architectural artistry of high-rise structures are constantly increasing, and in order to meet such modern requirements, it is necessary to diversify the functions of high-rise buildings and complicate the building form. At present, the main structural systems of high-rise buildings are: frame structure, shear wall structure, frame shear structure, and tube structure. Different structural systems determine the size of the load-bearing capacity, lateral stiffness, and seismic performance, as well as the amount of material used and the cost. This project is mainly concerned with the seismic design of frame shear structural systems, which are widely used today.
