Fabricated tough PEC recycled concrete beam-column joint with profiled composite floor
A fabricated tough PEC recycled concrete beam-column joint with a profiled composite floor slab comprises a PEC column, and a recycled concrete floor slab, a profiled steel sheet and an H-shaped steel beam are sequentially arranged on one side of profile steel of the PEC column from top to bottom. The H-shaped steel beam is in an H shape formed by an upper flange, a lower flange and a middle web plate, the H-shaped steel beam is broken into two parts, one part is a short beam welded to the PEC column, and the other part is a long beam; semicircular grooves are formed in the upper and lower flanges of the right side of the short beam at the broken position, semicircular groove butt joint plates are arranged at the upper and lower flanges of the left side of the long beam, and the semicircular grooves are in butt joint with the semicircular groove butt joint plates; the rectangular end plate is located on the right side of the short beam and connected with the web in a welded mode, the rectangular end plate is located on the right side of the long beam and connected with the web, and the middle of the end plate is provided with four holes used for containing shape memory alloy cables and connected through a clamp; the dog bone type connecting plate is connected to the inner side of the upper flange at the disconnected part of the short beam and the long beam; residual displacement and damage of the structure under the action of an earthquake can be reduced, and the maintenance cost after the earthquake is saved.
一种带压型组合楼板的装配式韧性PEC再生混凝土梁柱节点，包括PEC柱，PEC柱的型钢一侧从上至下依次再生混凝土楼板、压型钢板和H型钢梁；H型钢梁由上下翼缘以及中间腹板构成H形，H型钢梁被断开成两部分，一部分是焊接于PEC柱的短梁，另一部分为长梁；断开处的短梁右侧上下翼缘处设置半圆形凹槽，长梁左侧上下翼缘处设置半圆形凹槽对接板，半圆形凹槽与半圆形凹槽对接板进行对接；矩形端板位于短梁右侧，与腹板焊接连接，矩形端板位于长梁右侧，与腹板连接，端板中部均有布置四个孔洞用于放置形状记忆合金线缆并通过夹具连接；狗骨式连接板连接于短梁与长梁断开处的上翼缘内侧；本发明能降低地震作用下结构的残余位移和损伤，节约震后的维修成本。
