近年来,混凝土单管塔在通信行业开展了不同规模的试验与试点,但各类产品需要通过若干次真型试验来定型.本文采用试验与SAP2000模拟建模方法对混凝土单管塔正常使用极限状态下变形、裂缝结果进行研究,并将试验结果与计算结果进行比对分析.分析结果表明:杆塔变形的试验与理论值基本一致;试验初裂与理论值处于同一荷载加载阶段.
In recent years,concrete monopole towers have undergone various scales of testing and pilot pro-jects in the telecommunications industry.However,multiple full-scale tests are still required to finalize the de-signs of different product types.In this paper,both testing and SAP2000 simulation modeling are used to inves-tigate the deformation and crack behavior of concrete monopole towers under normal usage limit states.The theo-retical calculations are compared with the results of full-scale tests.The analysis indicates that the experimental and theoretical values of tower deformation are in closely aligned,and the initial cracking loads observed in the tests align with the theoretical values at the same loading stage.
