基础拉梁

主要介绍了大跨度钢结构的结构布置、其动力特性及各工况下的内力分布、基础拉梁、摇摆柱、梭形钢结构桁架柱、滑动支座的设计等内容。

The design of the big-span steel structure is introduced for structural layout , and its dynamical characteristics and internal forces distribution under different load cases , foundation tie bar , swinging column , steel shuttle-shaped truss column and sliding bearing etc , are presented .

大直径扩底墩墩帽及基础梁（拉梁）设计

The Design of Pier Template and Foundation Beam ( Tie Beam ) of Large - Diameter Belled Pier

通过分析墩帽及基础梁（拉梁）的受力状态，提出了墩帽及基础梁（拉梁）的设计方法。

By analysing the bearing condition of pier cap and foundation beam ( tie beam ), this article gives the design approach of pier cap and foundation beam ( tie beam ) .

设计人员一般在一柱一桩基础上设置双向拉梁来约束桩顶水平位移，以保证基础的侧向稳定性，但转角位移却不能避免。

Designers know it is necessary to connect single pile cap with base beams to ensure the stability of cap , but the rotation of cap is not avoidable .
