In wood processing, the log section are the external constraints of geometry and calculation of volume saw the key factors, the precise shape of the logs to identify the timber processing industry has become the primary problem.
设计了基于包络原理的激光检测机构的机械部分;应用无线数据采集模块,实现数据的无线传输;应用计算机软件平台实现对检测数据的计算分析得出原木形状参数及材积,并通过程序编译完成对原木截面形状的二维和原木三维图形的模拟再现及图形处理。
So in the analysis model of frame structures,the rigid region should be set on all rigid ends of the beam,as a result the more reasonable calculation span of frame beam can be used for structure analysis to make the control section consistent with the calculation section of the beam.
混凝土框架梁端的实际控制截面位于梁、柱界面处,而不是与梁端相连的柱的轴线处,所以结构模型中所有框架梁的刚接端均应设刚域,使框架梁的计算跨度更合理,使梁端的控制截面与计算截面相一致,使设计能根据梁柱界面处的组合弯矩确定梁端截面配筋。
