Study of different tubular systems on the lateral load resistance

Abstract

Worldwide, high rise construction is recent trend in the building development. Steel has many advantages which includes flexible framing system, assembling, less weight to height ratio, high availability and it doesn’t harm environment. That’s the reason steel has been mostly used material in the high rise buildings. Previously gravity load was considered as an important factor in the construction design. With the demand of high rise buildings now seismic force and lateral force is also gaining more attention. In High rise buildings tubular frames are most commonly used structural system. Among this framed and bundled are most famous tubular frame systems. Precise analysis is required for its design. Tubular systems are used in exterior as well as interior, mainly for resisting seismic force and lateral force. In this research Framed tube system and bundled tube system is analysed for lateral load resistance using ETABS software. For analysis purpose 8 stories steel building was considered. Different factors like lateral displacement at top floor, base shear, storey drift and steel weight were analysed for framed and bundled tubular system.
