转换梁上部框架结构的设计与计算

Design and Calculation of Frame Structures above Transfer Beams

针对转换梁结构上部的普通框架梁常因大跨转换梁的竖向变形导致框架梁支座内力超常增长的情况,采取“先放后抗”的设计理念,通过在上部框架梁端部设置后浇带释放因转换梁变形而急剧增大的上部框架梁内力,达到安全合理、经济方便的目的,同时提供另一种解决问题的思路。

Inner forces at supports of ordinary frame beams above the transfer structure always increase abnormally due to vertical deformations of long-span transfer beams. In this article, a design concept of ＂release and resistance＂ is adopted. Post cast strips located at ends of the frame beams can release the increased internal forces caused by deformations of transfer beams to achieve safe, reasonable, economical and convenience purpose.
