碩士 === 朝陽科技大學 === 建築及都市設計研究所 === 97 === There are many commercial boards in the street to attract people. Most of store owners like to use vertical mounted type of board that is cantilevered to the store front facet. When the gale occurred, the board will suffer different level of effects and damages. This research will use the wind tunnel experiment to discuss the wind influence on commercial board in the street discussion. The pressure stress on various spots that produced in the wind field, we can examine the influence of the board component. This research will take unified board type of city streets as object to do the experiment and analysis. The research goals are in the discussion of wind field influence and the degree of the wind pressure on commercial board. Using the experiment and taking the intersection and the central part of the street as sample, we will measure wind pressure that exerted from the front and back surface of the board in order to understand the influence conditions and offer the suitable corresponding proposals. This experiment takes the low-speed tunnel test and equivalent wind speed laminar field to process. Using suitable street and building model with instruments, the author measure the wind pressure change on board and carry out the test. Taking windward and leeward conditions of acting wind, the corresponding experiments will offer the maximum and minimum pressure value and their locations of the board from the instruments. From the analysis, we will find out the part of the board that need strengthen and to reduce even avoid the damage of the commercial board in order to promote public safety.
