Advanced Examples

In this section, several advanced examples are presented to demonstrate how to model structures in fire using OpenSees.

Thermo-mechanical analysis

• Restrained beam subjected to temperature rise
• Single beam subjected to temperature rise compared to a real test
• Composite beam example
• Steel frame example
• Cantilever beam modelled using beam and shell elements
• Demonastration of column pull-in action
• Thermal expansion of free end of a cantilever beam
• Temperatue load on fixed beam
• Thermal bowing of pinned beam
• Temperatue load on a simple truss

• Modelling flat concrete slabs subjected to furnace fire
• Modelling composite slabs subjected to furnace fire

Heat transfer analysis

• Heat transfer of concrete slab exposed to standard fire
• I-section beam subjected to localised fire

Hybrid Fire Simulation/Testing

• Dual-3D hybrid simulation of Cardington Plane Frame Fire Test

Benchmark cases

Material comparision

• Comparision of material models: Steel01Thermal, Steel02Thermal and SteelECThermal using a simple restrained beam

Benchmark examples

• Simply supported plate subject to experimental temperatures
• Simply supported composite beam subjected to test temperatures
