在现代建筑中，一个主要的可用性考虑因素是由于居住者的活动而导致的地板过度振动。随着高强度、轻质材料在建筑结构、更长的楼层跨度和更灵活的框架系统中的使用，楼板振动正成为一个更重要的设计考虑因素。商场、人行道和大厅以及体育馆的地板系统相对较轻，容易出现振动问题。对于设计界来说，准确预测这些振动和评估地板系统的方法并不容易。对人群诱发荷载的特性进行了研究。这些特征包括人群的密度、人群运动的随机性、人群活动以及个体之间的时间交互。建立了各种荷载特性对楼板体系动力响应影响的分析方法。制定了商场、体育馆和人行道中承受人群诱导荷载的楼板的设计指南。
One major serviceability consideration in modern buildings is excessive floor vibrations due to occupant activities. Floor vibrations are becoming a more important design consideration with the use of high-strength, light-weight materials in building structures, longer floor spans, and more flexible framing systems. Floor systems in shopping malls, pedestrian walkways and concourses, and gymnasiums are relatively light and susceptible to vibration problems. Methods for accurate prediction of these vibrations and evalution of floor systems are not readily available to the design community. An investigation is made into the characteristics of crowd-induced loads. These characteristics include the density of the crowd, randomness of crowd movement, crowd activity, and temporal interaction between individuals. Analytical procedures are developed to determine the influence of each load characteristic on the dynamic response of floor systems. Design guidelines are developed for floors in malls, gymnasiums, and walkways subjected to crowd-induced loads.
