拱梁平面 meaning in English

arched girder plane

After an introduction to the research on the software for the design of the variant steel arched girder construction , the creation of the structural model , the structure of the supporting seat , the design of the variant arched girder , and the measures taken to ensure the stability of the plane surface of the arched girder , the thesis goes to study the methods for the hoisting and the angle setting of the long - span arched girders , as well as the bolting of the axle pin in the hinge support
论文首先对变异钢拱架结构设计可采用的软件、结构模型的建立、支座构造形式、变异拱梁的设计，以及保证拱梁平面外稳定所采取的措施等进行了研究，然后研究了大跨度变异钢拱架弧形梁吊装、角度的调整、铰支座穿轴销等的施工方法，最后对施工完成后的位移进行了实际量测。
