Meanwhile , arched roof is generally set on beam at the top of pillar . since column adaptor may has displacement ( specially horizontal displacement ) , load - carrying capability of the structure will step down , and bending rigidity of the column also has emphatic influence on it 同时，拱型屋盖一般是通过边梁支承在柱子上，由于柱顶产生位移(尤其是水平位移) ，支承在柱子上的拱型屋盖的承载力较固定支座的拱型屋盖有所降低。
Thousands of spiritual seekers converged on the tel aviv cinema , a grand old movie theater located near the city center , to hear the good news about their true self . even this cavernous hall could not seat all the people yearning to hear master s message about their true homeland 为了聆听关于内在真我的福音，灵性追寻者聚集在市中心附近一家大型剧院中，来宾众多，甚至拱型演出大厅都无法容纳全部渴望倾听师父带给他们真正故乡信息的听众。
After practicing the quan yin method , however , he was born anew . this time , master not only delivered him from his fate , but also made his toes normal . his face became rosy like that of a newborn baby and he also became plumper 未印心前，他的双足十个脚趾都呈拱型，任何鞋穿不了多久，就被他的脚趾撑破了，而且腰弯背驼，一副未老先衰相修行观音法门后，喜获重生，这次师父又帮他化解厄运，十根足趾全都伸直，脸色有如新生婴儿般红润，人也变胖了。
It is shown that small - curvature arch support is very superior to trapezoidal support in mechanical properties , and has higher bearing capacity and better self - stability , so that such problem as short - distance coal gateways and lower branch coal gateways can not be bolted and is difficult to support in high pressure can be solved effectively 结果证明：小曲率拱型支架力学性能远优于梯形支架，支撑能力大，自身稳定性良好，有效解决了近距离和下分层煤层巷道不可锚且在强压下难支护的问题。
Acmr is a kind of cold - formed thin - walled steel structure . stability of these structures is a critical factor on their load - carrying capacity . furthermore , cold - formed thin - walled steel structure is sensitive to initial defectiveness and boundary condition , so all these issues need to be studied further 金属拱型波纹屋顶结构属于冷弯薄壁构件，稳定问题是影响其承载能力的关键因素，而且冷弯薄壁构件对初始缺陷、边界条件相当敏感，这些都值得进一步的研究。
The maximal load - carrying capability of the arch support is calculated by adopting mechanical model of curved beam based on its force analysis , and relationship between bearing capacity coefficient of small curvature arch support and radius and span of curved beam is gained based on supporting capacity comparison of curved beam and straight beam 采用曲梁模型进行了支架系统的受力分析，得到其最大承载能力；通过与直梁支架承载能力相比较，得到了小曲率拱型支架承载能力系数与曲梁跨度和半径的影响关系。
On the basis of simplified calculation model presented by doctor wangxiaoping , some finite element models are set up . by finite element model program sap93 , an analysis of static models of 18m - span and 30m - span w666 acmr in different supporting conditions is made . also a study on the relation between definite support displacement , which reflect variational stiffness of substructure represented by steel column or reinforced concrete column , and load - carrying capacity mechanical performance is made too 本文以w666金属拱型波纹屋顶为研究对象，沿用王小平博士的简化计算模型，对18m 、 30m跨波纹拱两端不同支座形式(铰支、固支和弹性支座)分别利用有限元计算程序sap93进行计算分析，研究波纹拱在不同跨度，不同支座形式下，不同外荷载作用时对该结构受力性能及稳定承载力的影响，同时分析下部支承钢柱、钢筋混凝土柱的刚度变化体现为允许支座位移的大小与结构受力性能及稳定承载力之间的关系。
