摘要:The 2006 Yogyakarta earthquake resulted in collapse of several traditional buildings in Yogyakarta,including joglos.This fact indicates that joglos are quite vulnerable to low-frequency ground shaking.The stability and rigidity of a joglo building are provided by the core of the building,i.e.the rong-rongan structure,in which connection of sakaguru (the column)-sunduk (the long span beam)-kili (the short span beam) has a rigid characteristic.This rigid rong-rongan structure behaves elastically during an earthquake event,and attracts large inertia force.This research aims to increase the structure performance of the rong-rongan by adding “SANTEN-fuse,” an earthquake vibration damper,and by changing the joint connection of sakaguru-sunduk-kili to be that of a pin connection,but not changing the physical appearance of rong-rongan.Santen,whose function is to transfer the load of the roof from blandar to sunduk and from pangeret to kili,is modified so that it has frictional damper characteristic.This “SANTEN-fuse” can resist shear force up to certain level before it slides and acting as a damper.With the reduced stiffness,which leads to reduced inertia force,the overall structural responses are expected to be lower.An experimental quantitative method was used by doing a simulation using SAP2000 software to verify the idea.The pendopo dalem Yudonegaran a joglo house in Yogyakarta was chosen as a case study.Non-linear time history analysis was conducted.Simulation results showed that the proposed modification of rong-rongan structure by using “SANTEN-fuse”,performed better than the original rong-rongan structure.
