Software Verification Examples for SCADA Pro 41 B2. Analysis & Design of Concrete Structures B2.1. Rectangular Plate under Vertical Loading Problem Description A two dimensional rectangular plate, subjected to vertical loading is examined (Figure B2.1.1). Geometry, Properties, Loads and Loading Combinations The plate of dimensions 9.75m x 4.75m has 20cm thickness. Material is reinforced concrete of modulus of elasticity 29GPa and Poisson ratio ν=0.20. Τhe concrete strength class is C20/25 while the class of reinforcing steel is B500C. The centre distance of the reinforcement from the plate edge is 20mm. Τhe plate is subjected to its self-weight (ε c =25.0kN/m 3 ), to a uniformly distributed permanent load 2kN/m 2 and to a uniformly distributed variable load 5kN/m 2 . Two cases of loading combinations are examined. In the first one (Comb1) the value of the participation factor of all loads is equal to 1.0. In the second case (Comb2) the participation factor of permanent loads is equal to 1.35 while the corresponding one of the variable load is equal to 1.50. Two cases of boundary conditions are studied. According to the first one (Support Case 1) the plate is simply supported along the long sides while the short sides are free. In the second case (Support Case 2) the plate is simply supported along all sides. The analysis is based on the finite element method, using plate elements. Support Case 1 Support Case 2 Figure B2.1.1. Rectangular Plate examined for two cases of boundary conditions Assumptions During analysis, Kirchhoff theory of plates has been adopted.
