The structure analysis studies and design - essentials of the continuous hollow slab beam erected as simple - supported beam in advance 先简支后连续预应力空心板梁受力分析研究及设计要点
So the high effective pre - stressed reinforced concrete hollow slab with medium strength spiral - continuous - ribs steel bar has a good prospect 因此，以中强螺旋肋钢丝为受力筋的预应力空心板具有广阔美好的发展前景。
Realized from the punching cracking characteristic , its punching shear capacity is related closely to the number of hollows crossing the punching cracks 根据柱端冲切裂缝分布特性可知,空心板的抗冲切承载力与柱边裂缝穿过空心体的数量有密切联系。
Thus , it is an effective way for our prefabricate part industry to develop high ef - fective pre - stressed reinforced concrete hollow slab so as to go out of the depress 因此，依靠技术进步，发展高效预应力空心板是适应我国预制构件行业走出困境的一条行之有效的途径。
On the basis of the theoretical analysis and the finite element calculating , the conclusions show that the cast - in - place reinforced concrete hollow flat - plate floor should adopt the calculating method of the flat - plate floor 通过理论分析和有限元计算，本文认为现浇钢筋混凝土空心板无梁楼盖应按无梁楼盖体系的设计方法进行结构计算。
Based on the nonlinear analysis theory of the reinforced concrete flexural member , this paper explores a numerical analysis program for the pre - stressed and hollow - core concrete slabs with mid - strength spiral - ribs steel wires 运用钢筋混凝土受弯构件非线性全过程分析的基本原理，本文编制了中强螺旋肋钢丝预应力混凝土空心板的数值分析程序。
Thus the numerical analysis testifies that the service stages of the pre - stressed and hollow concrete slabs with mid - strength spiral - ribs steel wires can also be separated to the elastic stage , cracking stage and failure stage 数值分析程序验证了中强螺旋肋钢丝预应力混凝土空心板的工作阶段也可分为弹性工作阶段、带裂缝工作阶段和破坏阶段。
Based on the design case of shuangjianghe bridge on the segment from tongdao to jili in g209 national high - way which was being built , the linear cantilever slabs was made to fit transition curve of the route 摘要以国道g209通道至吉利段改造工程中的双江河大桥设计实例，研究位于小半径缓和曲线上预制空心板梁的外悬臂折线逐步逼近缓和曲线线形，与桥上路线线形一致。
Compared with the normal flat - plate floor , the cast - in - place reinforced concrete hollow flat - plate floor has two special characteristics . to produce the hollow floor , the hollow columns are pre - buried in the floor . there are concealed wide - flat beams between the frame columns 和普通平板无梁楼盖相比，现浇钢筋混凝土空心板无梁楼盖有两个突出的不同点，一是在楼板内预埋空心圆筒形成空心楼板，二是在框架柱之间设有暗扁梁。
By introducing the structural design features of large - span prestressed hollow plate with cast - in - situ concrete of shooting gym for beijing olympic games , it is expounded section determination of the hollow plate , and is also described some structural measures and construction requirements 摘要通过介绍奥运射击馆工程中，大跨度现浇混凝土预应力空心板的结构设计特点，阐述空心板截面形式的确定，并且对一些构造措施和施工要求进行说明。
