摘要:
通过对典型的钢桥塔塔-基连接构造形式进行数值分析与简化分析,得到了埋入式连接和螺栓锚固式连接的受力特性,并对埋入式连接和螺栓锚固式连接的力学性能进行了比较和分析。结果表明:埋入式连接整体刚度大,竖向抗压承载力高,但当有弯矩作用时,混凝土基础中可能产生拉应力; 在钢桥塔水平向荷载作用下,螺栓锚固式连接有较强的抗弯、抗拔能力,但极限抗压承载力相对较小。
Abstract:
The force characteristics of submerged connection and bolt anchored connection were summarized through analyzing the construction form of the typical connection for steel pylon and concrete foundation structures by using finite element models and simplified mechanics models. Also, the mechanics performances of the two connections were compared and analyzed. The results indicate that submerged connection has powerful integer rigidity and vertical compression bearing capacity, but there maybe occur tensile stress in the concrete of the upper part of foundation when bending moment exists. Bolts anchored connection has strong capacity of bending resistance and withdrawal resistance under the horizontal loads of steel pylon, but the ultimate compression bearing capacity will be smaller relatively.
