Abstract:

In many cases, seismic appraisal of existing structures is carried out by the two-step method and seismic strengthening of R.C. frame structures is solved just based on rough calculation or experience of designers, which may lead to either lack of safety or too conservative in design. According to some related criteria and experts’ experience, a computer program is developed specially for seismic appraisal and seismic strengthening of R.C. frames(not more than 10 storeys)in this paper. Because the program has a friendly interactive interface and a “navigating” function, users with a little knowledge of civil engineering can use the program to finish the job of seismic appraisal and seismic strengthening of R.C. frames. After seismic appraisal is completed, three strengthening methods can be selected, which are increasing the components’ section with reinforced concrete, encasing them with angle steel and adhering steel plate on their surfaces, respectively. The design work based on the program will be completed more accurately, reasonably and quickly. At the same time, a great deal of manpower, material resources and financial resources can be saved.

现有结构的抗震鉴定采用两级鉴定法, 设计人员往往根据粗略计算和经验进行加固, 导致加固方案不安全或过于保守.本文依据有关国家标准及专家经验, 编制了钢筋混凝土框架抗震鉴定与加固计算机软件.该软件具有“导航”功能, 人机界面友好.具有一般土建知识的用户即可通过使用该软件选用加大截面法、钢构套法或粘钢法对钢筋混凝土框架进行较准确、合理、快速的抗震加固设计, 并节省大量的人力、物力和财力.
