已建好的砖混结构房屋常因使用功能发生改变而需要进行加层改造,从而导致房屋荷载的传递途径发生改变,故需对原有建筑进行加固处理。文章针对加层改造建筑物的具体特点,为确保加层后房屋的使用安全,合理分析与确定加固、加层设计方案和处理措施。 The built-up brick-concrete structure houses often need to be retrofitted due to changes in the use of functions, resulting in a change in the way of transmission of the house load, so the existing buildings need to be reinforced. In order to ensure the safety of the buildings after the addition of layers, the article analyzes and determines the design and treatment measures for the reinforcement and addition of layers in order to ensure the specific characteristics of the buildings that have been retrofitted.
