A Design Method for Shockproof and Isolated Overhead Corridor Structure in High Intensity and High Wind Pressure Area

Abstract

The invention discloses a design method for an overhead corridor structure for shock absorption and isolation in areas with high intensity and high wind pressure, and relates to the design field of overhead corridor structures for shock absorption and isolation. The structural design of the overhead corridor located in a high-intensity and high-wind pressure area must ensure the limit state of the bearing capacity and the limit state of normal use at the same time. Because the single buildings on both sides of the connection usually have different natural vibration periods, the use of seismic isolation bearings in the corridor The shock-isolation layer is formed between the monomer and the horizontal force of interaction, which can greatly reduce the horizontal force of interaction, and the deformation can be suppressed through the vibration-damping device, so as to achieve a better structural design. Based on the principle of standard design spectrum, the invention proposes a design method for seismic-isolation overhead corridors suitable for high-intensity and high-wind pressure areas in view of the situation that the lower part of the seismic-isolation layer is a building structure and the quality of the upper structure of the seismic-isolation layer is smaller than that of the lower structure . The invention obtains the excitation at the support of the corridor through the single seismic response, and obtains the horizontal seismic design spectrum used in the design of the upper structure of the seismic isolation layer of the corridor through envelope regression.

Description

technical field [0001] The invention relates to the design of an overhead corridor structure for shock absorption and isolation, and specifically discloses a design method for an overhead corridor structure for shock absorption and isolation in areas with high intensity and high wind pressure. Background technique [0002] As the carrier connecting the building structures, the overhead corridor can not only realize the functional requirements, but also ensure the beautiful appearance of the building. When designing the overhead corridor structure, on the one hand, it must ensure that it can bear the load itself, and on the other hand, it must also consider the force transmission between the corridor and the connected monomers. As a connecting body, the overhead corridor and the connected monomers form a conjoined structure. There are usually two types of connection between the linker and the monomer: strong connection and weak connection. When the connection is strong, the...

Problems solved by technology

The overhead corridor structure that uses seismic isolation bearings to form the seismic isolation layer, because the corridor structure itself has a large span and low mass, it is unreasonable to refer to the conventional seismic isolation structure and use the shock absorption coefficient to design
