Abstract
The need for high rise buildings in big cities like Jakarta is very urgent right now. Requirements regarding the quality of concrete, speed and ease of implementation have become demands. The Tamansari Hive Office Park is designed to meet these terms and conditions. This building consists of 3 basement floors and upper structure of 12 stories. The basement and shear wall structures are constructed from cast in place conventional concrete. While the top structure uses precast components for floor plates, beams and columns. This paper will describe the shape of beam, column and floor modeling in precast system structures. Indonesia is one of areas affected by earthquake events. Thus, earthquake load is a problem to be considered. Design of earthquake resistant buildings follows the provisions in Building Requirements for Structural Concrete (ACI 318-11), Indonesian Earthquake Resistance Design Procedures for Building and Non Building Structures (SNI 1726 – 2002) and some related regulations, particularly design regulations concerning precast buildings. The earthquake-resistant concept of this building does not use the concept of strong columns weak beam as earthquake absorbers, but uses the concept of self centering as described in the PRE cast Seismic Structural System (PRESSS). This concept is implemented with Unbonded Post-Tensioned Precast Concrete for Special Moment Frames that connect beams and columns which meets the requirements of the ACI T1.2-03 Special Hybrid Moment Frames Composed of Discretely Jointed Precast and Post-Tensioned Concrete Members and ACI 550.3M-13 Design Specification for Unbonded Post-Tensioned Precast Concrete Special Moment Frames Satisfying ACI 374.1. In addition, the beam is also connected to a column with normal reinforcement as a weak connection. Meanwhile the column to column connection uses grouted splice sleeve. The diaphragm has important uses in the distribution of seismic forces, so that elements such as beams and columns accept the forces according to their rigidity. Hollow core slabs are oneway slab elements that are sheet-shaped and have a certain size. The elements must be arranged into unity, in order to function as a rigid diaphragm. This paper explain the using a method of construction without scaffolding for this project. This method will speed up the installation of precast components and avoid work disruption at under the floor. While the column to column connection using grouted splice sleeve.
