Bridge vase pier top reinforcing bar design method
The invention discloses a bridge vase pier top reinforcing bar design method, which is characterized by comprising the following steps of calculating pier transverse tension based on a pier top vertical force design value, in a formula Td=2Nd((e-b)/4h0 + a/2), Td is a transverse pull rod internal force design value of a pier top; wherein Nd is a vertical force design value of the pier top; e is the center distance of the double supports; b is the transverse width of the support padstone; a is the horizontal distance from the actual stress line of the equal-width section of the pier to the edge; h0 is the effective height of the section; reinforcement design is conducted on the pier top of the vase pier according to the formula that gamma0Td is smaller than or equal to fsdAs; gamma 0 is a bridge and culvert structure importance coefficient; wherein fsd is a tensile strength design value of the common steel bar; As is the area of a common steel bar in the pull rod. The method is advantaged in that calculation difficulty of the vase pier structure is greatly simplified, the method can be suitable for calculation of the bridge vase pier, design efficiency of reinforcing bars at the top of the bridge vase pier is improved, meanwhile, the engineering risk can be reduced, and investment is saved.
本发明公开了一种桥梁花瓶墩墩顶配筋设计方法，其特征在于，包括以下步骤：基于墩顶竖向力设计值，计算桥墩横向拉力计算：Td＝2Nd((e‑b)/4h0+a/2)公式中，Td为墩顶的横向拉杆内力设计值；Nd为墩顶的竖向力设计值；e为双支座的中心距；b为支座垫石横向宽度；a为桥墩等宽段实际应力线距离边缘水平距离；h0为截面有效高度；根据公式γ0Td≤fsdAs，对花瓶墩墩顶进行配筋设计；γ0为桥涵结构重要性系数；fsd为普通钢筋抗拉强度设计值；As为拉杆中的普通钢筋面积。本发明极大的简化了花瓶墩结构的计算难度，可以适用于桥梁花瓶墩的计算，提高了桥梁花瓶墩墩顶配筋设计效率同时能实现降低工程风险、节约投资。
