Abstract
The Greater Jakarta Light Rail Transit Project (LRT Jabodebek) is an infrastructure project that utilizes lead rubber bearings (LRBs) to reduce seismic demand on structures. This seismically isolated system shall provide operational performance levels under design earthquakes. Nonlinear time-history analysis was used to evaluate the structural performance. Five pairs of scaled ground motions were used as the input motions for the time-history analysis. The ability of the lead rubber bearing to isolate the structures and dissipate earthquake energy will determine its effectiveness in achieving the targeted structural performance level. From this exercise, the targeted performance was achieved. In the last part of the paper, the construction documentation of the elevated structures is presented.
