多层钢筋混凝土隧道式房屋由于其固有的抗震性能和施工方便等优点，是地震高风险地区常见的结构形式之一。尽管它们在1999年土耳其地震中表现良好，而且这种结构分布在世界各地，但目前的抗震规范和设计规定对其抗震设计提供的指导不足。作为补偿措施，进行了一系列的模态和非线性静力分析，重点是隧道式建筑的特征动力行为，包括墙与墙和墙与板的相互作用的影响，扭转和开洞的影响的荷载传递机制和抗震性能。一个新的公式显式确定其基本周期，除了建议的响应折减系数和钢筋混凝土剪力墙开口周围。
Multi-story reinforced concrete tunnel form buildings are one of the common structural types in regions prone to high seismic risk due to the buildings inherent earthquake resistance and ease of construction. Despite their good performance during earthquakes in 1999 in Turkey, and abundance of such structures scattered worldwide, current seismic codes and design provisions provide insufficient guidelines for their seismic design. As a compensatory measure, a series of modal and nonlinear static analyses are conducted by emphasizing the characteristic dynamic behavior of tunnel form buildings including impacts of wall-to-wall and wall-to-slab interaction and effects of torsion and wall-openings on the load transfer mechanism and seismic performance. A new formula for explicit determination of their fundamental period is developed in addition to a recommended response reduction factor and reinforcement detailing around shear-wall openings.
