多层钢筋混凝土框架结构改造与异形柱应用

The Improvement of Multi-layer Reinforced Concrete Frame Structure and the Application of Special-shaped Columns

工程结构特性和工程实践证明了钢筋混凝土框架结构缺点的存在。时代在前进,工程设计亦应不断剔除落后,充实先进、开拓创新,跟上时代前进的洪流。在有内隔墙的框架结构中将方形柱改造成异形柱;将框架结构与砌体结构融为一体,即砖砌体加钢筋混凝土"箍"(梁、柱),集合砌体框架两结构的优点,避其缺欠。推出"梁柱墙联合承重协同工作"的框架结构模式,它更适用于抗高震级的抗震结构建筑中。优化工程结构,改善使用功能,提高工程价值是工程设计不断追求的目标。

It has been proved in practice that reinforce concrete frame structure has its problem.The use of special-shaped columns can be a good alternative for the frame structure with interior walls.The developed model combines the advantage of the frame structure with that of masonry structure,which could provide an accurate modeling of coordinated load bearing function of beams,columns and walls.It will be more applicable to the construction of anti-seismic structure in high-intensity earthquake zones.
