论文摘要
在许多情况下，结构框架中的光束连接是半刚性的，但由于其计算复杂性和设计方法的短缺，它们被认为是理想的刚性或固定的。在本文中，连接被认为是刚度可变的线性旋转弹簧。此外，本研究的主要贡献是一种初步的设计方法，可以通过针对不同框架的图表来考虑连接的半刚性行为。这些图将框架的三个特征相关联。帧连接的刚度，帧元素的几何特性及其横向位移。当需要框架连接的所需刚度时，可以使用这些图，而框架的所需响应，框架的尺寸以及其元素惯性的第二刻的比率是已知的。另一方面，它们可用于获得光束长度与圆柱长度的比率，以及梁的第二次惯性与圆柱的惯性与框架连接的刚度以及唯一已知的数据以及x和y方向框架网格的数量以及其所需响应的比率。
In many cases, beam to column connections in structural frames are semi rigid, but they are considered to be ideally rigid or pinned due to their computational complexity and shortage of designing methods. In this paper, connections are considered as linear rotational springs with variable stiffness. Moreover, the main contribution of the present study is a preliminary design method of moment resisting frames, considering semi rigid behavior of connections, by means of presented diagrams for different frames. These diagrams relate three features of a frame together; stiffness of frames connections, geometrical properties of frames elements, and its lateral displacement. These diagrams can be used when the required stiffness of frames connections is needed while the desired response of the frame, dimensions of the frame and the ratio of second moment of inertia of its elements are known. On the other hand, they could be used to obtain the ratio of beams length to columns length and the ratio of second moment of inertia of beams to columns alongside the stiffness of frames connections while the only known data is the number of frames grids in X and Y directions and its desired response.
