Abstract
In design and analysis of seismic reinforced concrete floor slabs, diaphragms should be designed as one of the important part of member design. Theoretically the floor slabs could be considered as rigid, semi-rigid and flexible floor diaphragms, however, in reality this should be implemented based on the assumption of the in-plane stiffness which should be determined appropriately. The code does specifically mentioned the definition of this matter but the rigidity boundaries for design practice is relatively uncleared. An attempt was done through a selected design example by using the general commercial softwares for finite element method to calculate these boundaries. This paper elaborate in detail of this exercise from practical point of view consideration.
