Etabs 2017
1. Chinese Steel Frame Design
Chinese steel frame design now supports the 2018 requirements for GB50017-2017, GB50011-2010 and JGJ99-2015.
2. Modeling
2.1 General quadrilateral meshing of floor areas
2.2 User-defined internal mesh for shells
2.3 Improved merging of floor areas by removing common edges
2.4 Ability to automatically add rigid-zone areas over columns and walls
3. Analysis Modeling
3.1 New link property to represent high-damping rubber-bearing isolator
3.2 Multiple controlled displacements for static pushover analysis
3.3 Link properties can be used for line and area springs
3.4 Strain response for shell objects (walls and floors)
3.5 Option to control the slope of steep strength-drop in frame hinges
3.6 Improved convergence behavior for displacement-controlled nonlinear static load cases
3.7 Increased speed and reduced storage for running and displaying results of nonlinear load cases
