碩士 === 國立臺灣科技大學 === 工程技術研究所 === 86 === Due to the geography location,Taiwan has a lot of natural disasters,such as typhoon and earthquake.Internally,many researchers have spent a lot of time and human resources in researching earthquake,but the studying of the influence of weather proofing is quite few.Therefore,we start the research totest wind and rain resistance on buildings and we are going to probe into the method and equipment of the testing for weather proofing performance of exterior openings.Also,we are going to classify the internal weather document informationso that other researchers can use this study as a reference information. In order to make sure that the exterior walls and openings are qualified, we should use mock-up testing to test the exterior walls and openings.However, there are two different testing systems in Taiwan,there are some differences in testing equipment,conditions,and methods.We are going to engage in actual experiences to compare and explore the influence in testing result,while all relevant testing methods are used in experiences. In addition,about the testing machine in our research institute, we will not only explain the development,function,equipment and operation sequence but also describe the problems and solutions in the process of constructing. Then, we can understand this kind of machine more. Going through a series of practical experiences,we compare and analysis the same and different places about all kinds of testing methods and process. We also probe into the reasonable of the imitated weather condition.Due to the result of testing,there are five characteristics: 1.After the increasing pressure method of short term successive lashing is used ,the air leakage ofair permeability tests tend to reduce down. 2.When the pressure of air permeability tests are between 10 ~ 70 kgf/㎡,it will appear more stable linear relationship. 3.In the air permeability testing process of the JIS and ISO standard,the testing process of reducing pressure step by step is somehow meaningless. 4.Under the same pressure,the negative wind pressure has more influences than the positive wind pressure to exterior openings. 5.In the wind resistance watertightness test,if it is under the same pressure, long term pressure a ffect has more influences then sine air pressure pulse. As a result of the testing by our weather proofing testing research institute,we know we have to plan the part of pre-operation more carefully and we need to understand the feature, principle, and operation furth er more. Then,we can make the machine give full play to the original design condition. Besides,by the studying of testing methods, we can understand te difference of testing methods and the defect of internal testing standards. Finally,the conclusion of our research institute is that it could provide a reference information about building a testing machine and continuously put forward proposals about the weather proofing test of exterior openings.
