Analysis and Design of Multistory Building Using Different Structural Systems

Skeleton frame system and load bearing wall system are common structural system
being used in high-rise and mid-rise building. These systems may have significant
advantages and disadvantages against each other. The decision on using which system
may require careful justification in order to build an economical, easy, and fast-toconstruct
building beside the stability and the durability of the building. In this study, a
layout of a multistory building is to be designed using both systems. Both layout
systems are then will be analyzed for the same live load as a control factor. The overall
cost for the building is mainly depending on the quantity of materials used in the
construction. Comparing the quantity of materials used to build the building, the load
bearingwall system uses about 60% more concreteand steel reinforcement bars than the
frame system. The load bearing wall system also found to require only minimum wall
thickness with minimum reinforcement bars in the design. By reversing the calculation
to determine the reinforcement for the walls, it is found that the minimum wall thickness
with minimum reinforcement can stand the load of 1473.5 kN/ m length of wall while
the maximum loads on the wall is only 577.36 kN/m length of wall (about 50% of the
capacity). It is concluded that the frame system is suitable for any height and any floor
arrangement while the load bearing wall system is more suitable for building with height
morethan 30 storey with similarfloor layout in everyfloor..
