AI Technical Summary

Technical Problem

Existing seismic wall structures, particularly those using glass plates, face limitations in improving seismic resistance and wall strength ratios due to sudden transmission of external forces during earthquakes, leading to potential collapse.

Method used

A frame structure with a groove on its inner surface and a plate-shaped wall body within the groove, featuring elastic deformation of the groove bottom plate and outer peripheral plate portions to gradually transmit in-plane stresses, preventing sudden stress transmission and enhancing seismic resistance.

Benefits of technology

The elastic deformation of the frame and plate portions effectively prevents the collapse of the wall by gradually transmitting in-plane stresses, improving the wall's strength ratio and resisting external forces, such as those from earthquakes.

Abstract

In an earthquake-resistant wall structure comprising a frame having a groove on its inner surface and provided within the structural plane of a column-beam frame, and a plate-shaped wall having an outer edge located within the groove of the frame, the collapse of the wall is effectively avoided while exhibiting excellent wall strength. [Solution] The frame 10 has a plate-shaped groove bottom plate portion 16 along the outer peripheral end surface 30b of the wall 30, and the groove bottom plate portion 16 is provided adjacent to the outer internal space 19 and has a structure that elastically deforms in accordance with the relative movement of the wall 30 with respect to the frame 10 along the normal direction X of the bottom surface 11b of the groove portion 11, and a pair of elastic bodies 25 are interposed between both sides 11a inside the groove portion 11 and both sides of the outer peripheral edge portion 30a of the wall 30, and each of the pair of elastic bodies 25 is not adhered to at least one of the frame 10 and the wall 30.
