The structure for this project is a slab fixed along two edges. You will model it using 6 quadrilateral (i.e., 4noded) plate elements. The structure and the mathematical model are shown in the figures below. It is subjected to selfweight, pressure loads and temperature loads. The purpose of this tutorial to create the model, assign all required input, perform the analysis, and review the results.

Slab is 300 mm thick

Material Constants

E, Density, Poisson, Alpha — Default values for concrete

Supports

Nodes along 2 adjacent edges; fixed against rotation and translation

Primary Loads

Load 1: Selfweight
Load 2: Pressure Load of 300 kg/m^{2} acting vertically downwards
Load 3: 75 degree F uniform expansion, plus top surface is 60 degrees hotter than the bottom

Combination Loads

Case 101: Case 1 + Case 2
