May 7, 2018 - Reinforced Concrete Spiral Helical Staircases Reinforcement Details.Set of CAD dwg drawing details for spiral / helical reinforced concrete staircases. Different types of staircases can be made by arranging stairs and landing slabs. Step by step procedure of Bar Bending Schedule of Doglegged Staircase . >> A reinforced concrete staircase for office use is shown in Figure 1. ! At the end lower the stair supported by a beam and continuous with the floor slab. 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. CAD .dwg file CAD .dxf file PDF unlimited… Main reinforcement runs in the longitudinal direction, while shrinkage reinforcement runs in the transverse direction.

� Design the staircase by using concrete grade 25 and strength of reinforcement of 500 N/mm2. Reinforced Concrete Stairs Cross Section Reinforcement Detail This is a typical Reinforced Concrete Stairs Cross Section Reinforcement Detail, in CAD drawing that needs to be included alongside with every structural drawing that includes a concrete staircase to show correct reinforcement placement at the start, middle and landing part of the stairs. Plan and Cross Section Views of Stairs The next phase includes the positioning of any necessary additional upper rebars followed by the placement of their distribution bars. Learn how to calculate steel reinforcement required for staircase. Special attention has to be paid to reinforcement detail at opening joints, as shown in Figure 10.8. The stairs slab is designed for maximum shear and flexure. The staircase detailing is conducted through bar bending schedule. The standard width of any stair may be between 1.1 to 1.6 m. In public use building like malls, cinema, shopping center larger width of stair can be used.
