SECURITY STRUCTURE TO BE MAIN FOCUS IN DEVELOPMENT STORY BUILDING
GIVE FOCUS ON SECURITY ASPECTS STRUCTURE
Structural safety is an absolute requirement of a high rise building. Especially when the multi-storey building is Grade-A office buildings. World Capital Tower is a high-rise building with grade-A. To that end, would need to meet the criteria so that the structure of the building is structurally safe. Therefore, PT. GISTAMA INTISEMESTA has been appointed as a consultant to the World Capital Tower structure.

WORKING STRUCTURE OF THE COMPREHENSIVE - INTERNATIONAL STANDARD
PT. GISTAMA, as the leading structural consultants appointed to handle the structure of the World Capital Tower, has given the design parameters in the design of structures that meet the safety and comfort of the World Capital Tower. Construction materials were used following the standard ISO-03-2847-2002, with the start of Grade Concrete f'c = 30 MPa to 35 MPa. For columns and sheer concrete wall using a higher grade, ie F'c = 40-50 MPa. To avoid the influence of vibration and discomfort in the office, the office live load reaches 2:50 kPa, and dead loads in accordance with SKBI -1.3.53.1987. Building height above 200m, with rules based on the P2B and Construction Supervision Team Building, requires us to hold a wind load testing. This needs to be done by a professional service. To test windload, PT. WINDTECH has been appointed to conduct the test in Sydney, Australia. Average wind load used was approximately 30.5 m / s. With held wind load test, expected above 200m building is structurally safe, and provide for pedestrian comfort and also for tenants in the office. In addition, PT. GISTAMA INTISEMESTA also been thinking about the earthquake load, which is based on standard RSNI-201X 03-1726 and ASCE 7-10. For earthquake loads, building population also needs to be calculated, and also carried out for safer SSRS when soil test. All these factors, coupled also with other calculations, PT. GISTAMA has been designing the most effective and efficient structure, so that more earthquake-resistant buildings, and is also not affected by weather conditions Jakarta.
