Study on Interactive Computer Program for Seismic Appraisal and Seismic Strengthening of R.C. Frame Structures

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.
