摘要

摘要: 为研究高强度钢材钢结构的受力性能,了解国内外最新研究进展,促进该类新型绿色节能结构体系的更广泛应用,并为今后的相关研究提供参考和指导,对国内外高强度钢材钢结构的工程应用和最新的研究进展进行总结,特别是清华大学近期所做的一系列试验研究,包括高强度钢材的静力力学性能、韧性和循环荷载下的本构模型,构件截面的残余应力分布、受压钢柱的稳定性能和滞回性能、高强度钢材板件螺栓连接的延性和承载力,高强度钢材钢框架的抗震性能以及高强度钢材钢结构的相关有限元分析等内容。结果表明,高强度钢材钢结构在材料、构件和结构体系三个层面上都具有明显的优势,但现有的设计方法并不完全适用,需要发展新的设计理论和计算公式,以期更合理、安全地应用高强度钢材钢结构。

Abstract: High strength steel has been gradually applied in construction industry.As the strength of steel increases,the property of toughness degrades to some extent,particularly in the case of application at low temperature.Therefore,it is necessary to study the impact toughness of high strength steel.Impact toughness tests of 14 mm thick Q460-C steel at low temperature were performed,Charpy impact power level was compared with that of 60,90,120,and 150 mm thick Q345 steel at the same temperature respectively,besides the scanning electronic microscope of the Charpy-type specimen fracture surfaces with different temperature points were analyzed.And the results showed that:1)The impact toughness of Q460-C steel decrease with the descending temperature;2)Between 20 ℃ and-20 ℃,the low temperature impact power level of 14 mm thick Q460-C was lower than that of 150,120,90 mm and 60 mm thick Q345 at the same temperature;3)The influence of steel strength on low temperature brittleness of Q460-C was less obvious than that of steel depth on that of Q345;4)The fracture appearances of Charpy-type specimens of Q460-C,which break at-20 ℃ had finished the transition form ductile to brittle on the whole,with a large of significant brittle characteristics.Meanwhile,a Boltzmann function fit analysis was made on Charpy impact test results of Q460-C,obtaining-11.1 ℃ as the brittle ductile transition temperature.Test results showed that the low temperature brittleness of Q460-C and its welding seam were apparent,to which much attention should be paid.
