Purchased product contains : .dwg file .dxf file .pdf file fully customisable A MUST HAVE DETAIL One of the most useful structural details when designing for reinforced concrete. *uC]��>�ɛ���o R.C.C. Details that are belong to changing situations on the existing floor of stairs are sketched of plan & cross section view with 1/10 and 1/20 scale. Design the staircase by using concrete grade 25 and strength of reinforcement of 500 N/mm2. Special attention has to be paid to reinforcement detail at opening joints, as shown in Figure 10.8. Cantilever slab supported on a reinf. ! Different types of staircases can be made by arranging stairs and landing slabs. One of the most difficult design tasks is now ready and available to use with every project. During the final phase of the positioning of the staircase’s reinforcement, the lower rebars (in red color) are tied to the distribution bars to their proper position. The theoretical procedures employed in the structural analysis of stairs is the concept of an idealised line structure and when detailing the reinforcement for the resulting stairs, additional bars should be included to limit the formation of cracks at the points of high-stress concentration that inevitably occur.
