Novel multi-ribbed composite wall structure system with three anti-vibration defense lines

Abstract

The invention discloses a novel multi-ribbed composite wall structure system with three anti-vibration defense lines, which includes a first anti-vibration defense line point contact type X-shaped filling building block, a second anti-vibration defense line reinforced concrete multi-ribbed frame grid unit, a third anti-vibration defense line reinforced concrete invisible outer frame and acast-in-situ reinforced concrete floor, wherein the point contact type X-shaped filling building block and the concrete frame grid are contacted at four corner parts, flexible material is filled between the point contact type X-shaped filling building block and the concrete frame grid, 10-50mm slit is arranged between the side surface of the multi-ribbed frame grid unit and an outer frame column, and the multi-ribbed frame grid unit and top surface and bottom surface of an outer frame beam are anchored in the frame beam through rib column longitudinal steel bars to realize rigid connection. The structure system has three specific anti-vibration energy-dissipating defense lines, each defense line sequentially performs dominant defense effect under earthquake with different grades, thereby reaching the purpose of dissipating earthquake energy and reducing earthquake reaction by stages; and load transmission path is clear, mechanical model is simple and visual, thereby being convenient for realizing elaborate design of the multi-ribbed composite wall structure.

Description

technical field [0001] The invention relates to a dense rib composite wall structure system with three anti-seismic defense lines, and belongs to the field of anti-seismic and shock-absorbing technology of building structures. Background technique [0002] Earthquake is a sudden natural disaster that endangers the safety of people's lives and property, and is extremely destructive and harmful. Especially in densely populated and industrially developed cities and regions, the losses are even more severe. So far, people's understanding and research on earthquakes are still in progress. Due to the complexity of building structures, the uncertainty of earthquake motion, the limitations and ambiguity of people's understanding of earthquakes, the accuracy of structural calculations, especially the accuracy of seismic analysis calculations, the variability of material properties and construction and installation, and other unpredictable factors Factors make the calculation results...

AI Technical Summary

Problems solved by technology

[0005] (1) The contact length between filling blocks and rib beams, rib columns, and outer frames is unclear, resulting in unclear stress models, unintuitive load transfer paths, and the role of blocks in the seismic process cannot be accurately predicted;

[0006] (2) Under the action of external force, due to the surface contact between the block and the sash, the block failure forms are various, and shear failure may occur, and compression failure may occur, or a certain degree of shear failure occurs first and then turns to Compression failure, and the block failure sequence is unstable;

[0008] (4) It is a common practice for those skilled in the art at this stage to connect the densely ribbed composite wallboard and the outer frame column through rib beams, and this results in the seismic effect and damage that the outer frame and densely ribbed composite wallboard need to play. In many cases, the wall panel and the outer frame are damaged at the same time, so the ductile failure sequence of "wall panel first, then frame" cannot be realized, and the structure actually only shows two anti-seismic defense lines
