ETABS 2015 is the most sophisticated and technologically-advanced software product available to structural engineers today. It defines the future of building design software, setting the stage for unsurpassed capability and efficiency worldwide.

 

Introducing Automation of Performance-Based Design

Performance Based Design (PBD) is a major shift from traditional structural design concepts and represents the future of earthquake engineering. These new procedures help assure that the design will reliably meet a desired level of performance during a given earthquake.

The fundamental component of PBD is nonlinear dynamic analysis where an attempt is made to capture the real behavior of the structure by explicitly modeling and evaluating post-yield ductility and energy dissipation when subjected to earthquake ground motions. ETABS 2015 introduces new special purpose options and algorithms for the practical and efficient application of these procedures.

  • Automated PBD hinges and procedures based upon ASCE 41-13
  • Stable and Fast Nonlinear Analysis (FNA) implemented for PBD
  • Steel and concrete fiber models for shear walls and columns
  • Automated Nonlinear hinges in shear walls based upon user/design reinforcing
  • Steel and concrete material models with performance levels (confined and unconfined)
  • Material strain as performance measure for D/C ratios
  • Automated generalized displacement constraints for strain evaluation
  • Several new hysteresis options for nonlinear hinges
  • Options for hysteretic stiffness and strength degradation
  • Output averaging of responses over several time history runs
  • Quasi-static (Dyanmic) option for Static Pushover analysis of complex models
  • D/C ratio plots and tables for fast performance evaluation
  •  Automated Bucking Restrained Brace (BRB) modeling (Star Seismic)
  • Friction-spring hysteretic damper and Bilinear Maxwell oil damper property
