| Summary: | Mixed used building Citraland is a high-rise building with a combined function of residential and office to be built in the city of Bogor. Concept of vertical buildings are applied due to the lack of available space, but on the other hand the need for housing and places to work is always increasing. Design of Mix Used Building Citraland consists of 17 floors and 3 basement floors that work as parking lots. This thesis aims to design a foundation system that can carry the load from the structure and to design a retaining wall that can provide safety against lateral soil forces.
Diaphragm wall with a thickness of 1 meter and a total length of 26 meters with excavation to a depth of -12.8 meters is used as retaining wall. The retaining wall will be reinforced by ground anchor reinforcement at depth of 3, 6, 8.5 and 10.5 meters. Analysis of the stability of the retaining wall was carried out using PLAXIS 2D software with stepwise construction modeling. The position of the groundwater table is high and needs to be drained using cutoff dewatering system so there will be no significant land subsidence outside the excavation.
The foundation used is a pile foundation with a diameter of 0.8 meters with a total pile length of 55 meters and a pilecap thickness of 2 meters. Driven pile foundations are used because they are considered more economical than drill piles. The foundation load is obtained from the results of the structural analysis with ASD combination loading. Axial bearing capacity analysis and settlement are calculated
manually while lateral bearing capacity analysis is calculated using LPILE software. Pilecap reinforcement and punching shear analysis were modeled using CsiSafe software.
