When dismantle the machine, firstly, stop the suspension coop on the lower 2 sections of the standard sections, the operation staff go on the suspension coop top, the hoisting machine loosen rope, lift the pillar with small shaft, pull out the horizontal pin of pillar, let the pillar fall slowly to thedismantled section's middle angle bar, insert the horizontal pin again. At this time, loosen the connection screw of standard section with spanner, hang the shaft of hand crane on the upper angle bar, sway the shaft of hand crane upward, separate this standard section from the next section, and lay itin the suspension coop, dismantle the other standard section for the same method, and turn the shaft to another direction, draw the lifting wire rope tightly, the operation staff leave the suspension coop, open the lock stopping instrument, fall the suspension coop to next position and lock the brakeinstrument, the operation staff return to the top of suspension coop, continually dismantle note: forbid the staff leave on the top of suspension coop or in the coop when the suspension coop is running

Compared with the ordinary plate beamless roof, the cast-in-place reinforced concrete spatial core beamless roof has two prominent diversities, one is buries the hollow cylinder in the floor to form the hollow floor in advance, the other is equipped with wide-flat beams between the frame.

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，二是在框架之间设有暗扁梁。

The curve continual steel box Liang shearing force stagnates the effect finite element analysis box section Liang has the big flexural rigidity and torsional stiffness, the stress performance good, spanning ability big, on the bridge the field of vision open and so on the merits, is in the bridge design the commonly used structural style, when receives under the dead load or the symmetrical live load function winding, because the lifting surface detrusion causes its bending stress to present the non-uniform distribution condition along the Liang width direction, this phenomenon is called "the shearing force to stagnate the effect".

曲线连续钢箱梁剪力滞效应的有限元分析箱形截面梁具有较大的抗弯刚度和抗扭刚度、受力性能好、跨越能力大、桥上视野开阔等优点，是桥梁设计中常用的结构形式，在受恒载或对称活荷载作用下挠曲时，由于翼板的剪切变形致使其弯曲应力沿梁宽度方向呈现不均匀分布状态，此现象称为&剪力滞效应&。

One flush end-plate external joint under monotonical loading and the other four joints under cyclic loading were tested. Failure modes and the effects of reinforcement ratio and concrete in column flange were synthetically considered during cyclic loading. Results of the experiments show that external flush end-plate composite joint also have quite hysteretic behaviors, better strength resistance and stiffness that are worth to promotion in seismic area.Based on experimental results and plastic analysis simplified formulas on moment resistance of semi-rigid composite joints were introduced.

本文对1个半刚性端板连接组合边节点进行了单调静力加载试验并对4个半刚性端板连接组合边节点进行了循环加载试验研究，主要探讨了节点的破坏模式以及混凝土板内纵向钢筋配筋率和柱翼缘内填充混凝土对节点性能的影响，试验结果表明端板连接组合边节点依然具有良好的滞回性能，较好的延性和耗能能力，是一种值得推广的半刚性梁-柱节点形式。
