项目摘要
9416262 Bennett Construction with masonry infills remains very popular, particularly in the low to moderate seismic zones of the eastern/central United States. Infill walls may have both beneficial and detrimental affects on the building behavior under seismic loading. Infill walls increase the stiffness of a building, shift the structure's center of stiffness, and affect the forces in the framing possible causing premature failure of frame members. The infills can also provide a redundant load path for both horizontal and vertical loads, thus have a positive influence on the structural behavior. The objective of this project is to use data from the Northridge earthquake to characterize the beneficial and detrimental performance of infills, correlate the performance to numerical methods, and evaluate the risk associated with both unreinforced and reinforced infills. Key aspects of in-plane performance of infills that will be examined are the details of the interface between the infill and bounding frame, the alignment of the infill with the bounding frame, and the effect of the infill on the bounding frame. With respect to out-of-plane behavior, the stability of the panel and applicability of arching theories under dynamic load will be examined. This research will impact both high and moderate seismic zones. The level and priority of retrofit required for infills in high hazard zones may be less than anticipated. Perhaps just as significant is the impact on infill construction in low to moderate seismic zones, which cover most of the central/eastern Untied States. A better understanding of infills, which has to be related to actual seismic performance, is needed to take full advantage of infill construction in moderate hazard seismic zones. ***
9416262班尼特建筑与砖石填充仍然非常受欢迎,特别是在低到中等地震带的东部/中部的美国。 填充墙对建筑物在地震荷载作用下的行为既有有利的影响,也有不利的影响。 填充墙增加了建筑物的刚度,改变了结构的刚度中心,并影响了框架中的力,可能导致框架构件的过早失效。 填充物还可以为水平和垂直荷载提供冗余荷载路径,从而对结构性能产生积极影响。 本项目的目标是使用北岭地震的数据来表征填充物的有利和有害性能,将性能与数值方法相关联,并评估与未加固和加固填充物相关的风险。 将检查的内嵌的平面内性能的关键方面是内嵌和边界框架之间的界面的细节、内嵌与边界框架的对齐以及内嵌对边界框架的影响。 对于平面外的行为,将检查板的稳定性和在动态载荷下的稳定性理论的适用性。 这项研究将影响高和中等地震区。 高危险区填充物所需的改造程度和优先次序可能低于预期。 也许同样重要的是对低到中等地震带的填充建筑的影响,这些地震带覆盖了美国中部/东部的大部分地区。 需要更好地了解填充物,这与实际的抗震性能有关,以充分利用中等危险地震区的填充物施工。 ***
