预制一种带翘翼的单波圆柱壳体,多个横向连续排列,构成连波壳盖,可用作房屋顶盖。其翅翼相对,便于防水构造处理。(见图1、2) 下面仅介绍这种壳体内力的近似表算法。 (一)基本假定假定壳体受载弯曲变形后,横截面仍保持原有的平面状态,其形状、尺寸均不变。 (二)应用条件 1、壳体跨度与波宽之比大于3; 2、壳体横截面对称,荷载均布且对称; 3、壳体纵向边缘自由。 (三)内力计算(忽略翘翼和出檐部分的影响) 1、壳体截面尺寸及力学特征值(见图3) 已知: 壳体跨度(横隔间距) L
Prefabricated single-wave cylindrical shell with a wing, a plurality of transversely arranged continuously, constitute a wave shell cover, can be used as a roof. Its wings are relatively easy to deal with waterproof construction. (See Fig. 1, 2) The following only describes the approximate table algorithm of this kind of shell internal force. (a) The basic assumption is that assuming that the shell is subjected to bending deformation, the cross-section still maintains its original planar state, and its shape and size do not change. (II) Application conditions 1. The ratio of shell span to wave width is greater than 3; 2. The shell is symmetrical in cross section and the load is uniformly distributed; 3. The longitudinal edges of the shell are free. (c) Internal force calculations (ignoring the influence of the flaps and rakes) 1. Shell section dimensions and mechanical eigenvalues (see Figure 3) Known: Shell span (diaphragm spacing) L
