Research And Development On Reliability Appraisal Programs Of Masonry-Concrete Structures

As time goes on, the construction industry in China will step into the third period which emphasize modern reconstruction and strengthening. Many of the existent buildings will not meet the demand of use during the next cycle unless they are appraised and strengthed.Some improper factors in course of current appraisal work are pointed out in this paper. For example, using design software to analyse the structure and using the ratio of actual steel and calculated steel instead of that of bearing capacity and load effect to decide the grade of the component don't meet the demand of criterion.The measures above will lead to inaccurate conclusion.On the other hand, appraisal work also need to be intelligentized and roboticized.Researching and developing appraisal software can resolve these problems properly.This paper which based on current criterion investigate the theory of structure reliability appraisal programs development and implemented the reliability appraisal program of masonry-conrete structure elementarily. This program has a friendly interface and is easily operated. Some of the problems such as establishing check plan, analysing the datum automatically, selecting actual parameters of every component, calculating the ratio of bearing capacity and load effect accurately and so on are resolved in this program. Besides, an appraisal report can be created automatically with the result of structure analyse and the information input by the user in an interactive way.These approaches are common in reliability appraisal programs of masonary-conrete structure and other appraisal programs.
