Tarumanagara University Campus 1 Sky-bridge Structure Evaluation

Abstract

In this study an evaluation of the structure of the sky-bridge at Tarumanagara University campus 1 on earthquake regulations SNI 1726 : 2019. The sky-bridge connects the two buildings, parking building (8 floors) and the main building (21 floors). Type of support on the sky-bridge in the parkirng building is multidirectional pot bearing and in the main building is fixed pot bearing. The modeling of pot bearings in the ETABS program is modeled as a link property element. Based on the evaluation results, checking on the dimensions of installed pot bearing components have qualified the requirements set by AASHTO LRFD Bridge Design 2012. Based on earthquake redundancy factors, pot bearing on the 7th floor cannot be adjusted lateral deformation required is greather than maximum deformation limit provided by pot bearing, while based on earthquakes with strong factors, pot bearing on the sky-bridge are incorrect due to the lateral deformation that occurs. From the results of the study concluded that use pot bearings as support of sky-bridge 7th floor is not appropriate when checked against earthquake regulations SNI 1726: 2019.
