Due to their high strength and overall performance, the panels can be used as division and partion wall even the wall is very high and wide. Only steel structure should be used for fixing which is unstalled inside the wall and it is unnecessary to add wall posts. The anti-blast performance is 1.5 higher than that of brick wall.

由于强度高，整体性能好，因此可用作层高高、跨度大的墙体间隔，只要简单地采用钢结构锚固，型钢埋设于墙体内，大跨度，层高高的墙体就无需增加墙面的柱体，其抗冲击性能是一般砌体的1.5倍。

Light-gauge steel residence is a new type of residential building system which is composed of cold-formed steel frame and wallboard.

Based on the cold roll forming steel, its characteristic of roll-forming and deforming rule was analyzed.

以冷弯型钢中的槽钢为例，分析了其辊弯成型的特点及变形规律。

Compared with reinforced concrete floor, steel deck possess the advantage of thin wall, light in mass, but owing to smallness of damp, weakness of dissipation of energy, comfort possibly dissatisfies applicability required. Therefore, this paper first calculates and analyses dynamic property of new style steel deck; according to single footfall curve, ascertaining hominine walking excitation; utilizing time-history analytical method, calculating peak acceleration response of floor slab under excitation, and analyzing peak acceleration response proceeding from different board stride, different damping ratio as well as different profile.

相对于钢筋混凝土楼板而言，虽然钢承板具有壁薄、质轻的优势，但由于阻尼小、耗能差，其舒适度可能会不满足适用性的要求，为此本文首先计算和分析了新型钢承板的动力特性；根据单步落足曲线确定了人的行走激励；利用时程分析法，计算了楼板在行走激励下的最大加速度响应，并对不同板跨、不同阻尼比以及不同板型下的最大加速度响应进行了分析，结果表明这三种因素，尤其阻尼比和板型对于加速度响应的影响较大。

The lining layer of PO lining CS ware occludes firmly with the surface of the CS pipe.

钢衬PO管件衬里层与钢管表面咬合牢固是地地道道的紧衬型钢塑管。

Finally, through the instance of engineering, we can see that the steel dosage in steel honeycomb plank is smaller and the self-weight of the whole structure is lighter comparing with pyramided grid structure, and the steel dosage in portal strut with honeycomb laminated beam-column system is still smaller and the self-weight is still smaller comparing with steel I-beam,they will have a wide applied foreground.

最后，通过工程实例分析表明，在大跨度屋盖结构中，金属蜂窝板-杆空间结构体系比常规的四角锥网架结构具有用钢量低，结构整体自重轻等优点；在轻钢结构厂房中，采用金属蜂窝纯板片箱梁体系比一般H型钢结构用钢量更低，自重更轻，具有广泛的应用前景。

The ground floor column"s axial compressive force is especially big in high-rise buildings and skyscrapers . If using RC column ,it will lead short-column and "fat-column;if adopting steel structure ,it may reduce section area sharping,but its capacity of bearing erosion is weak,especially fireproof performance is its fatal weakness;SRC may not only reduce section area effectively,but also save steel,without the weaknesses in bearing erosion and fire-resistant capacity.

高层超高层建筑的底层柱轴力特别大，如果采用钢筋混凝土柱，会出现短柱和胖柱现象；采用钢结构，可以大大减小截面面积，但钢结构的耐腐蚀性能差，尤其是耐火性能成为它的致命弱点；而型钢混凝土既可以有效减小截面尺寸，又可以节省钢材，还没有腐蚀性和耐火性差这些问题。
