砖混结构托梁托柱结构设计

以小开间混结构改造为大空间结构为题，从基础设计、框架梁、柱的结构设计，作了详细的分析，特别对两种不同的结构形式，对改造中荷载的转移、内力的变化、构件工作性质等进行分析，并针对本工程提出了设计对施工的处理方案，为以后同类型的改造设计提供了参考依据。

Structure design of joists and supporting columns brick-concrete structure

Based on the transformation from small space brick ?concrete structure to the large, the writer analyses in detail the base design, frame beams and col umn' structure design. for the two different structural styles, such factors as the load's convert in transformation, inner force's change and components' worki ng property were considered. According to the project, the design?to?construct ion's disposal is put forward, thus references base is supplied to the same type of transformation design in the future.
