ANALISIS DESAIN TULANGAN PENGHUBUNG BORED PILE KE PILE CAP UNTUK MENAHAN GAYA GESER DASAR
Abstract
Damage that occurs in the foundation due to earthquake can have a fatal
impact on the building above it. The base shear force that occur on the building
foundation can cause bored pile and pile cap connections damaged. Therefore, it
is necessary to design connecting reinforcement that is stronger in resist the base
shear force when an earthquake occurs. This study analyzes five types of bored pile
to pile cap connecting reinforcement designs by modeling in ABAQUS CAE 6.14
software. The five designs consist of Model A with 45º bent connecting
reinforcement design, Model B with 60º bent connecting reinforcement design,
Model C with straight connecting reinforcement design, Model D with straight
connecting reinforcement design and additional P12-100 stirrups, and Model E
with straight connecting reinforcement design and additional P12-50 stirrups. The
analyzed bored pile foundation is a single pile, and the loading given to the model
is a static concentrated load in the lateral direction. The results showed that the
design of the bent connecting reinforcement had less strength than the straight
connecting reinforcement. However, the addition of stirrups and reduction of
stirrups distance on straight connecting reinforcement do not show an influence on
the strength of the connecting reinforcement. In addition, the displacement that
occurred in each model did not show a significant difference.
