【摘要】 单层平面索网玻璃幕墙结构具有柔性大、质量轻、阻尼小、自振频率低的特点,属风敏感结构, 但国内外并没有相应的抗风设计方法。推导了基于非线性随机振动理论的单层平面索网玻璃幕墙结构风振响应计算公式,并以此为基础提出了基于结构响应的单层索网玻璃幕墙结构的实用抗风设计方法,最后对该实用设计方法的准确性进行了校核。更多还原

【Abstract】 Because of characters of weak stiffness, light weight, small damping and low frequencies, cable net structure is sensitive to the fluctuating wind. However the proper wind- resist design of cable net facade is lacked. The practical calculation formula of the displacement variance and cable tension variance are deduced based on nonlinear random vibration, and the practical wind - resistant design method of the single- layer plane cable net are brought based on the structural response. The accuracy of practical wind-resist design method is testified.更多还原
