摘要
纵向变厚度钢板(LP钢板)是一种新型节约型绿色钢板,可广泛运用于工业与民用建筑、桥梁船舶及其他特种结构当中,其研发和应用对促进结构优化设计,建筑节能减排有重要意义。该文介绍了国内纵向变厚度钢板特殊的轧制与矫直技术,综述了钢板材料力学性能以及翼缘纵向变厚度工形截面简支梁在弹性和弹塑性阶段变形和承载性能的理论、试验和数值分析研究结果,得出了材料性能随厚度变化的规律,提出了翼缘纵向变厚度工形截面简支梁的承载力设计值和正常使用极限状态下变形计算方法。
Longitudinally profiled steel plate(LP steel plate) is a new type of green-saving steel product which could be widely used in industrial and civil buildings, bridges and other special structures. Its research and development have a great significance for structural optimization design and energy conservation in construction. The unusual rolling and straightening technology of LP steel plate is briefly introduced. The recent researches of Tsinghua University on material performance and component bearing capacity are comprehensively reviewed, which were studied by theoretical analysis, experimental and numerical simulation. The variation of material mechanical properties is concluded. The design methods of I-section beam with longitudinally variable thickness flanges for bearing capacity design value and deformation behavior at serviceability limit state are proposed.
