碩士 === 朝陽科技大學 === 營建工程系碩士班 === 97 === Steel structures which are tough and good to resist earthquake are used mostly in high-rise buildings. From 2005 to 2007, many electronics industry factories were built. A great amount of steel for buildings is used in that period in Taiwan. However, there was no formal construction specification for structural steel engineering. The construction codes of steel structures are still in development stage. At that time standards of test were slightly different due to the covering material on steel members. Some standards were slightly different when covering material on steel structure is fire retarding coating, fire retarding cotton or concrete. In this thesis, problems of the existing structural steel working processes and quality control, such as materials tests in factory, bolts establishment in the grounds, materials tests in construction sites, locking of lifting structural members, precision adjustment, welders and non-destructive testing and other things are studied. Those problems happened in construction sites and contrived problems occurred by engineers’ judgments are collected and investigated. At the same time, proposals of conflicts in existing specifications are discussed. Improvements in these conflicts are suggested. The construction code for steel structures was published in June, 2007. This code has been executed for two years. Some articles in the code are needed to be improved. The construction method will continue to be newly changed and technology will be continuously improved. So, the test standards should be revised too. Detailed rules based on the different natures of structures should be proposed. Hence, the quality of construction can be enhanced.
