MAIN FEATURES
Output: displacements, forces, stresses and strains (xy and orthogonal to the crack), displacement shapes, crack patterns, crack widths (from post-processing), stress fields and animation videos.
P-delta (2ºorder effects): included through coordinate updating.
Mass and damping: lumped and consistent mass matrices, Rayleigh damping models (mass and initial stiffness proportional), and modal damping models.
Materials: uniaxial cyclic models for concrete (confined and unconfined), steel (elasto-plastic, isotropic, kinematic, with Baushinger (i.e. Menegotto-Pinto)), biaxial cyclic models for reinforced concrete (orthotropic smeared-crack models (i.e. Compression Field Models)), uniaxial models for spring (contact) elements (linear, bilinear, compression/tension-only, gap...)
Elements: linear-elastic frame element, nonlinear (flexural) frame element, nonlinear frame element with flexure-shear interaction (Timoshenko), linear-elastic membrane element, nonlinear membrane element, layered shell elements, spring (contact) elements.
Types of Analysis: eigenvalue, linear static, nonlinear static (monotonic and cyclic, imposed displacement or forces), and nonlinear dynamic (external force, earthquake).
