PDL : Additional dead point load (kN or kip). WLL : Additional distributed dead load (kN/m² or kip/ft²).). g : Unit weight of concrete (kN/m³ or lb/ft³)Īpplied loads WADL : Additional distributed dead load (kN/m² or kip/ft²). Instantaneous €: Time factor for long-term deflection n : Poisson’s ratio, typically equal to 0.2. Months 3 fy : Reinforcement yield strength (MPa or psi). Material properties fcu : Concrete cube strength (MPa or psi). of load € time(m factor or to more Llong : Longer side length of the slab, takenyears parallel the5X-axis (m or2.0 ft). Lshort : Length of the short side of the slab,Duration taken parallel to the Y-axis or ft). dy : Effective depth for reinforcement in the shorter span direction, i.e.
List of symbols The design code symbols are used as far as possible :Slab geometry dx : Effective depth for reinforcement in the longer span direction, i.e. Slab edges can be made free, simply supported or continuous. Design loads include own weight, distributed and concentrated dead and live loads. Rectangular Slab Panel Design Design scope The program designs rectangular reinforced concrete flat slab panels. One-Way Continuous Slabs And Beams The following sketches show some one-way spanning continuous slabs and beams. The slab spans in two directions as shown in the sketch the slab spans only in the shorter direction. Slabs Slabs may be simply supported and span in one or two directions. The design incorporates automated pattern loading and moment redistribution.ĭownwards redistribution The downward distribution method aims to reduce the hogging moments at the columns without increasing the sagging moments at mid span.
Section Design for Crack width.Ĭontinuous Beam and Slab Design The Continuous Beam and Slab Design module is used to design and detail reinforced concrete beams and slabs as encountered in typical building projects. Vertical loads include all dead load and live loads.Ĭoncrete Design using PROKON Beam and slab design There may be bending moments as a result of the frame action.Ĭarry all vertical loads to the soil. Slabs do this in bending and shear.īeams Transmit loads from the slabs to the vertical columns in bending and shear.Ĭolumns Columns carry all vertical loads to the foundations in compression. دورة في تصميم العناصر الخرسانية المختلفة باستخدام برنامجĬoncrete Design The concrete design modules can be used for the design of reinforced and pre-stressed concrete beams and slabs, columns, column bases and retaining walls.Ĭoncrete Structural Systems Floor slabs Transmit live loads as well as stationary dead loads to the horizontal beams, which are part of the frame.
