摘　　要：建筑结构在长期使用中面临着材料老化、强度衰减等问题,这不仅威胁着建筑物的结构安全,还影响其使用寿命,给人们的生命财产安全带来潜在风险。为提升建筑结构的安全性、可靠性,推动新材料与新技术的应用,开展建筑用复合材料加筋板-钢板连接结构的力学性能研究。将加筋板和钢板用两种不同方式连接成1、2两种结构样品,再分别用粘接+螺栓(结构1-A、2-A)、焊接+螺栓(结构1-B、2-B)加固连接,得到4个试样。用万能试验机测试其拉伸强度、剪切强度,并在不同热处理条件下对试样的剪切强度与弯曲强度进行测量。结果表明:结构2-B的载荷-位移曲线更高,拉伸强度更优,剪切强度相对更高。相比于结构1-A、结构2-A,1-B、2-B由于用焊接+螺栓加固,在高温下的剪切强度与弯曲强度较好,且结构2-B优势更大,力学性能更优。Building structures are faced with problems such as material aging and strength attenuation during long-term use,which not only threatens the structural safety of buildings,but also affects their service life and brings potential risks to people's life and property safety.In order to improve the safety and reliability of building structures and promote the application of new materials and technologies,the mechanical properties of the composite reinforced plate-steel plate connection structure for building were studied.The reinforced plate and steel plate were connected into 1 and 2 structural samples in two different ways,and then reinforced with bonding+bolts(structure 1-A,2-A)and welding+bolts(structure 1-B,2-B)respectively,and 4 samples were obtained.The tensile strength and shear strength were measured by universal testing machine,and the shear strength and bending strength were measured under different heat treatment conditions.The results show that the structure 2-B load-displacement curve is higher,the tensile strength is better,and the shear strength is relatively higher.Compared with structure 1-A and structure 2-A,structure 1-B and structure 2-B have better shear strength and bending strength at high temperature due to the reinforcement by welding+bolts,and structure 2-B has greater advantages and better mechanical properties.
