3d earthquake loading opensees series#
Stress-Strain characteristics via the OpenSees UniaxialMaterial Command for all number of materials Section geometry via series of Patches and Layers in the fiber section Two Section Geometries are presented The program calculates the coupled flexural and axial stiffnesses/strength by integrating strains across the section The OpenSees Fiber Section Command is used User specifies Uniaxial Section The inelastic, uncoupled, axial and flexural stiffnesses are defined at the section level The OpenSees Uniaxial Section Command is used User specifies:Īxial stiffness A Section Moment-Curvature characteristics via the OpenSees UniaxialMaterial Command Fiber Section The section is broken down into fibers where uniaxial materials are defined independently. Inelastic Elements OpenSees Force-Based Beam-Column Element Two types of sections The following types of models are represented in these examples:Įlastic Elements OpenSees Elastic Beam Column Element The elastic, uncoupled, axial and flexural stiffnesses are defined at the element level user specifies: E,I,A NOTE: gravity analysis is always included as part of the model building
