此程序可完成两等跨连续钢吊车梁的设计校核工作，并具有自动绘制内力包络图、输出计算书功能。
This program can complete the designing and checking of a two-span continuous steel crane beam, and it can also draw of internal force envelopes and output the calculation files.
本文的研究为连续钢吊车梁的设计提供了切实可行的方法，具有一定的理论意义和工程实用价值。
The studies in this paper provide a practical way to design a continuous steel crane beam. It has some theoretical and practical values.
在预应力加固设计方面，钢吊车梁与混凝土吊车梁不同，由于其刚度较小、挠度较大，当吊车荷载作用上去后，会引起水平拉杆作用效应增量。
The steel crane girder's rigidity is smaller and its deflection is larger, when the crane moves, there will be force increment in the prestressed horizontal tie.
在设有大吨位吊车系统的重型厂房中，吊车梁用钢量所占比例较大，对吊车梁的优化设计对工程造价影响很大，大跨多跨重型厂房吊车梁宜采用突缘变截面简支结构。
The weight of steel for crane beam has a great proportion in the total amount consumed in the construction of the heavy-duty plant with large-tonnage cranes.
但是，综观国内的钢结构设计软件，只是对简支吊车梁进行设计验算，还没有一款针对连续钢吊车梁的设计软件以满足工程建设的需要。
Currently, the domestic steel design software can only design and check crane beams with simply supported, there is no continuous crane beams software to meet the needs of projections.
