结合一个实际工程,对砖混-框架混杂结构进行分块抗震鉴定,分析加固重点。通过增设混凝土抗震墙、对原有砖墙进行钢筋混凝土板墙加固等手段,加强两者之间的协同工作能力,从而提高整体抗震能力。对于单跨框架,通过计算及构造,避免其成为抗震薄弱环节。对托换梁在底层砖墙拆除过程进行全过程监测,结果表明,托换梁可按承重墙梁进行分析。 Combined with a practical project, seismic masonry-block identification of block-concrete mixed structures is carried out, and the key points of reinforcement are analyzed. Through the addition of concrete seismic walls, the existing brick walls reinforced concrete slab wall and other means to strengthen the collaborative work between the two, thereby enhancing the overall seismic capacity. For single-span frame, through calculation and construction, to avoid it as a seismic weak link. The whole process of the underpinning beam demolition process in the bottom brick was monitored. The results showed that the underpinning beam could be analyzed by the load-bearing wall beam.
