摘要:
对具有复杂体型的“L”型和“T”型低层房屋风荷载特性进行了风洞试验研究．研究了屋面平均和脉动风压系数的分布规律以及体型系数，并与传统“一”型低层双坡屋面房屋的风荷载特性进行了对比分析．结果表明：30°坡角时，屋檐及屋脊附近因气流分离常形成较高负压，迎风屋面平均风压系数多呈环状分布；当屋面处于背风区域时，风压系数分布较均匀；“L”型和“T”型低层房屋与传统“一”型房屋相应各面体型系数变化规律有一定的相似性，但是必须考虑各面间的相互干扰使得其风压增大的效应．

 

 
Abstract:
Wind tunnel test on wind load characteristics of low-rise buildings with complex shapes of “L” and “T” were presented. The distribution rules of mean wind pressure and fluctuating wind pressure coefficient of roof as well as shape coefficients of each surface were analyzed in detail. The wind load characteristics of “L” and “T” shape models were compared with which of low-rise gable roof building with traditional shape of “-”. The results show that high suction is formed on eave and ridge of windward roof because of the flow separation. The pressure coefficient on windward roof shows ring-form distribution feature when the roof pitch is 30°. The distribution of wind pressure coefficient is relatively homogeneous when the roof is in the leeward region. The changes of shape coefficient on each surface of low-rise buildings with "L" and "T" shape have certain similar regularities with which of traditional building with "-" shape. The interference effect between each surface, which increases the wind pressure, must be taken into consideration.
