Abstract


Fire occurring in the building can cause fatal effects to the strength of building. Therefore, this research aimed at investigating the structural strength and capacity pre-fire, the remaining strength and capacity post-fire, and the structural strength and capacity after adding steel plate reinforcement. The field data involved the building of Tamansari Emerald Surabaya Apartment. The nominal moment of beam was controlled pre-fire and post-fire. The results of research demonstrated that the beam encountering fire would have moment capacity reduction at 300°C, 600°C, and 800°C by consecutively 0,0677%, 2,7569%, and 33,98% of the moment capacity in the normal condition. Furthermore, the reinforcement applied steel plate having the dimension 150×5 mm. Thus, the increasing moment capacity after adding reinforcement gained around 60 – 380 Kn.m.

Keywords
