Organisch bandbeschichtetes Stahl‐Feinblech – Ein Produkt mit besonderem Korrosionsschutz

Continuously organic coil coated steel sheet – A product with the special anti‐corrosion protection. Continuously organic coil coated steel sheet is a semi‐finished product with a finished surface. The product is used for production of component parts with a high utility value. Functional and decorative aspects are realized due to the optimized material composition. These flat products have a high corrosion resistance by the layered composition which creates the important functional base for thin‐walled elements. The respective layers of complete coating have active and passive factors for the anti‐corrosion protection – the cathodic protection is an important factor. Constructive measures strengthen the protection against the negative influences of the weather. A high quality standard of the anti‐corrosion protection was safeguarded by the specification of quality requirements, factory supervisions and surveillance by authorized institutes, amongst others in result of the DIN 55928‐8. The new standard DIN 55634 follows this tradition. In spring 2008 the blue‐print of the new standard is published. By the durable and flexible organic coating of the flat product also decorative aspects like design, color and gloss are achieved. Due to a differentiated color design gigantic structure get a kind and live appearance of industrial plants by their facades. Light weight elements manufactured by continuously organic coil coated steel sheet affords for enterprises to do a built public relations with sustainability.

Thermal stress measurement in steel plate strengthened by CFRP and aluminum alloy plates

In steel members strengthened by carbon-fiber reinforced polymer (CFRP) plates, the thermal stresses are introduced in the steel members, the CFRP plates and the adhesive layers when temperature changes because the linear thermal expansion coefficients of steel and CFRP are mismatched. As so far, the authors proposed a technique to reduce the thermal stress in steel members strengthened by CFRP plates, which involves bonding aluminum alloy plates with CFRP plates. In the proposed method, the thermal stress in steel member can be reduced so that there are negligible levels of stress in steel member when the cross sectional areas of CFRP and aluminum plates are designed to correspond to the coefficient of thermal expansion of steel, even though the thermal stresses are introduced in the CFRP and aluminum plates. In this study, to confirm the maintaining the thermal stress reduction in steel member by proposed method, thermal stress measurement in steel plate strengthened by CFRP and aluminum plates was carried out about 21 months. In this research, the thermal stress introduced in the steel plate strengthened by CFRP plates was also measured. Furthermore, to assume the thermal shear and normal (peel) stresses in adhesive layers, FE analysis with plane stress element was employed. As the result, it was shown the thermal stresses in steel plate with CFRP plate were able to calculate by using composite theory and measured temperature. Furthermore, in steel plate strengthened by CFRP and aluminum plates, the thermal stress introduced in steel plate was negligible-small through the all-season. It was found the thermal stresses in steel plate with CFRP plates as well as CFRP and aluminum plates were also estimated by using composite theory and measured temperature. In the steel plate strengthened by CFRP and aluminum plates, the thermal shear and normal stresses in adhesive layer glued to steel plate become smaller than that in the conventional CFRP bonded specimen. However, the shear stress in adhesive layers between CFRP and aluminum plates in proposed method was higher than the thermal stress in adhesive layers between CFRP plates in conventional method.

槽形钢-混凝土组合梁及其应用前景初探

提出一种适用于轨道桥梁的新型槽形(U形)钢-混凝土组合下承式桥梁,它是指在槽形截面的钢梁内侧浇筑混凝土,钢板与混凝土通过抗剪连接件组合成整体共同工作。这种结构形式不仅继承了传统混凝土槽形梁结构的特点,而且具有许多自身的优点,钢板可以代替模板,故无需模板或使用较少模板进行施工;结构受拉区外包钢板,既避免了混凝土裂缝暴露,又具有较好的防撞功能,结构的耐久性好。下层钢板在横向和纵向均可以充分发挥抗拉强度,大大简化了构造,减少钢筋绑扎、焊接以及横向预应力张拉的困难。对这种槽形组合梁截面形式的比选进行了初步有限元分析。结果表明,截面各参数对结构受力性能的影响程度不同,其中混凝土底部纵向肋宽度、混凝土翼缘厚度及腹板高度等是较敏感因素;温度和混凝土收缩徐变对结构受力性能的影响也较大。在竖向荷载的作用下钢梁底板和混凝土底板的中面纵向应力沿板宽的分布均表现出一定的剪力滞后现象。还指出关于这种新型组合梁今后值得进一步研究的问题。
