Fire ) for reinforcing building , moreover , what will happen about the bond behavior of the cohering face for the building under high temperature frequently such as metallurgy and chemical shop which are radiated under high temperature ( 200 - 300 ) , chimney wall ( 100 - 150 ) ? these are not clear and definite . so it is necessary to study this question through experiments 另外,对于经常处于高温状态下的建筑,如冶金和化工车间受高温辐射的结构(温度在200 300 ) ,烟囱筒壁(温度在100 150 )等结构,经过高温作用后,其粘结面的粘结性能会发生什么变化,这些目前都不明确,因此很有必要对这一基本问题进行试验研究。
With the theoretical analysis of beams strengthened by gluing steel plates , this thesis propose the formulas to calculate the capability of bearing bending under different forms of loading , and the worth of the common function coefficient of steel plates is suggested . at the same time , the concept of premature failure and the standard of failure are brought up . finally , the referencing formulas to calculate the rigidity and deflection of beams strengthen by gluing steel plates are proposed , and the calculating results cohere to the experimental results well 通过对粘钢加固梁的理论分析,文中给出不同形式粘钢加固的抗弯承载力计算公式,并对钢板共同作用系数提出了建议值;同时,文中提出了早期破坏的概念,并给出早期破坏的强度破坏准则;最后,对粘钢加固的刚度和挠度计算提出了参考公式,且与试验结果吻合较好。
The study aimed at the cohering face of concrete after high temperature is little . only did the da lian university of science and engineering carried out the study of the bond property of the new - old concrete after 200 in 1999 . in this paper , we use the basic mechanical index - splitting tensile strength to judge the mechanical property of the cohering face of the new - old concrete 本文的研究工作近年来国内外进行了大量高温下混凝土材料受力性能的试验研究和理论分析,但大都是针对混凝土本身,而对混凝土粘结面受高温影响的研究甚少,只有大连理工大学在1999年作了200c后新老混凝土粘结性能的研究。
