Model concrete and steel materials in perform-3d, including inelastic and confined concrete models, and assign them to sections. Examine stress diagrams and degradation parameters to prepare reinforced concrete member calculations.

Explore nonlinear analysis of reinforced concrete cross sections in Perform-3D, comparing lumped end-point nonlinearity with fiber hinge modeling for beams and columns.

Model reinforced concrete walls in Perform-3D to capture brittle shear and ductile bending, using inelastic shear sections, elastic shear materials, and rigid top beams for load transfer.

learn to assign elements in perform-3d by creating groups for columns, beams, walls, and string gates, deactivate p-delta if needed, and set a local axis for correct orientation.

Assign nodal and element loads, including walls, beams, and surface loads, using weight units; define load subgroups for different conditions and apply to trapezoid and triangle shapes.

Define two parameters before structure checks: drift and structure sections lateral displacements, read shear forces separately for columns and walls across all stories in 3D, and assign groups.

Define limit states for frames and walls, using rotations as plastic hinges, and set drift, shear, and material limits to meet life safety and collapse prevention criteria.
