An energy-dissipating joint-limb anti-seismic wall of a composite connecting beam with reinforced grouting-hole blocks and its manufacturing method

Abstract

The invention belongs to the field of anti-seismic technology of building structures, and particularly relates to a load-bearing wall of multi-storey buildings in villages and towns that adopts a composite coupling beam energy-dissipating type anti-seismic wall with reinforced grouting blocks and a manufacturing method; including block walls, coupling beams, Mild steel damper, single tendon core column, structural core column, horizontal tie bars. The present invention forms an effective constraint on the block wall through the joint action of the core column and the horizontal tie bar, which improves the integrity and seismic performance of the wall body; Composite connecting beams, and mild steel dampers are installed at the connecting parts of the connecting beams and the wall, forming multiple lines of defense for energy dissipation and anti-seismic of the combined limb seismic wall, which enhances the ductility and energy dissipation capacity of the wall.

Description

technical field [0001] The invention belongs to the field of anti-seismic technology of building structures, in particular to a load-bearing wall of multi-storey buildings in villages and towns, which adopts a composite joint beam energy dissipation type anti-seismic wall with reinforced grouting blocks and a manufacturing method thereof. Background technique [0002] In recent years, most of the major earthquakes occurred in rural areas, such as the Wenchuan Earthquake in 2008, the Yushu Earthquake in 2010, the Lushan Earthquake in 2013, the Zhangxian Earthquake in Min County in 2013, and the Ludian Earthquake in 2014, which caused serious casualties and Economic losses. What deserves special attention is that most of my country's seismic belts are currently in an active period, and destructive earthquakes are gradually showing a trend of high frequency and frequent occurrence. According to the survey, masonry structures account for more than 60% of the structural forms of...
