Abstract
this paper investigates the influence of multiple transverse web openings on the flexural behaviour of underground metro station
reinforced concrete (RC) beams. ,is problem is outlined with an actual underground engineering project, in which the web
opening used in the RC beams violates the current specifications. A total of five beams with different numbers of web openings are
fabricated and tested under static and cyclic loading conditions, thereby simulating actual operations in unfavourable conditions.
The results suggest that the existence of the openings decreases the loadbearing capacity, ductility, stiffness, and energy dissipation
ability of the RC beams. Moreover, the results show that the corners of the openings are the weakest parts of the beams. However,
additional reinforcements around the openings can partially mitigate the impact of the openings on the loadbearing and seismic
performance of the RC beams. ,e laboratory experiments presented herein not only provide guidelines for the use of RC beams
with web openings in actual engineering projects, especially underground projects where RC beams with web openings have
seldom been investigated, but also shed light on improving the related design specifications.
