Examples
- Frame - bracing structure is a kind of dual - system , among which the bracing system may be shear wall , reinforced concrete core , vertical truss , etc . in current design codes for steel structures , multi - story steel frames are divided into two types , sway and non - sway frames
支撑体系可以是剪力墙、筒体或支撑桁架体系。国家现行的钢结构设计标准在计算框架结构的稳定性时将框架结构分为有侧移和无侧移两类，分别确定其计算长度。 - According to eigenvalue equation ( general formula ) of the energy method of the plane steel frame structure stability , and considering the restriction of the end of the column of the main steel frame and function of deflection curve gained from the differential balance equation general resolution , we get the equation for calculating the length coefficient of the main frame structure stability of the steel arch gate and the resolutions are also given
根据平面刚架稳定性能量法特征值方程(通式) ，考虑弧形钢闸门主框架柱的柱端约束的特殊情况，求出挠曲线函数(试解函数)通解，得到弧形钢闸门主框架柱稳定性计算长度系数方程。其中弧门主框架主横梁式形框架的临界荷载比较现行规范推荐的有限元法简单方便、结果精确及物理概念明确等优点。 - For frames of more than 3 stories , the weakest story is first selected and a three - story sub - assemblage including the weakest column is taken out , and the proposed method is applied , the effective length of the weakest column is thus obtained , the effective length of the remaining columns are computed through a pre - defined relations . because the sub - assemblage included beams at far ends of the columns above and below the column under consideration , the far end condition ( hinged or fixed ) may be considered easily
对于更多层的情况，先判断薄弱层，再假定薄弱层的上下层柱远端的梁端约束全部提供给与薄弱层相邻层的柱，取出薄弱层及其上下层的梁柱，按前面处理两层或三层框架的方法可以得到薄弱层柱很精确的计算长度系数，相应导得其它层柱的计算长度系数。 - Steel structure of light - weight buildings with gabled frames is a widely used steel structural style in china at present . this paper starts with the deficiency of the specificaion in calculating the effective length factors of gable portal frames . when the gable portal frame subjected to the vertical uniform loading , it conducts the arch effect ? 1 . rafter axial force is large when the slope of rafter is big
门式刚架轻型房屋钢结构体系是目前广泛应用的一种结构形式,本文从规范中门式刚架柱的计算长度系数取值的不足出发,针对山形门式刚架在竖向均布荷载作用下产生的拱效应? ? 1 、斜梁倾角较大时产生较大的梁内轴力; 2 、产生跨变效应; 3 、高跨比较小的山形门式刚架会发生跃越失稳,采用整体分析的方法对山形门式刚架的稳定进行了分析。 - It is found that initial brace deflections have significant effect on the stiffness and strength requirement which are interdependent ; and there is a very unfavorable interaction between lateral braces and columns imperfections . the calculating simplified model of this paper is not same with that of the former references . although this model is correspondingly conform to actual thing , the formula of lateral braces will be applied to practice after it is proved by experimentation
首先研究了完全理想情况下，得出了时柱计算长度减至一半所需的刚度；接着综合考虑了柱子和撑杆的弯曲，利用有缺陷杆的轴压切线模量概念和分枝屈曲理论，考虑屈曲前变形和内力的影响，同时用ansys有限元软件进行分析，得出了同时考虑撑杆的刚度和强度的计算撑杆面积和撑杆设计内力的公式。
