本文引入换算截面的概念,提出了横向配筋或加混凝土薄带砖砌体地震时抗剪强度计算公式。当砖墙抗震强度不足时,在不增加墙厚的情况下,应用本公式,强化砖砌体的抗震能力,以使地震时墙体不开裂(或初裂),达到避免震后维修加固的目的,对六、七度地震区砖结构抗震加固有一定的实用价值。 In this paper, the concept of conversion section is introduced, and the calculation formula of shear strength for earthquakes with transverse reinforcement or thin-band reinforced concrete brick is proposed. When the seismic strength of the brick wall is not enough, applying this formula to strengthen the seismic resistance of the brickwork without increasing the wall thickness, so that the wall will not crack (or crack) during the earthquake, so as to avoid the post-earthquake maintenance and reinforcement The purpose is to have certain practical value for the seismic reinforcement of brick structures in the 6th and 7th earthquake regions.
