ETABS 17.0.0 Enhancements

Modeling

General quadrilateral meshing of floor areas

User-defined internal mesh for shells

Improved merging of floor areas by removing common edges

Ability to automatically add rigid-zone areas over columns and walls

Graphics

Improved DirectX Display

Analysis Modeling

New link property to represent high-damping rubber-bearing isolator

Multiple controlled displacements for static pushover analysis

Link properties can be used for line and area springs

Strain response for shell objects (walls and floors)

Option to control the slope of steep strength-drop in frame hinges

Improved convergence behavior for displacement-controlled nonlinear static load cases

Non-iterative event-to-event option for nonlinear static analysis

Increased speed and reduced storage for running and displaying results of nonlinear load cases

Performance Based Seismic Design
