Abstract: Common approaches to compute the yield and buckling resistances of gusset plates require knowledge of the lengths yc, ycf , yb, ybf, L1, L2, and L3, (Figures 2 and 7). While numerical values for these resistances have been presented in the literature, formulas for yc, ycf , yb, ybf, L1, L2, and L3 have not been published. This paper presents the derivation and validation of equations to compute these lengths. The equations are summarized in flow charts that can be incorporated into software for practical applications. The formulas provided for yc, ycf, yb, ybf, L1, L2, and L3 enable optimization of gusset plate design.

The National Earthquake Hazards Reduction Program (NEHRP) ecommended Seismic Provisions for New Buildings and Other Structures is a well-known technical resource document for improving national seismic design standards and model building codes. Each edition of the NEHRP rovisions has been developed based on the most recent advancements in earthquake engineering and research. The 2020 NEHRP Provisions ontinues to apply the current state-of-knowledge in earthquake engineering for mproving the seismic design of uildings and other structures. It presents a set of recommended improvements to the ASCE/SEI 7-16 Standard: inimum Design Loads and Associated Criteria for Buildings and Other tructures, and nine resource papers on new concepts, suggested future development, and technical information in support of the recommended improvements. The NEHRP Provisions is developed and evaluated through an expert-based consensus process to ensure validity and quality of the recommended new changes. It is intended primarily for use by ational standards and code organizations and earthquake engineering rofessionals.

The innovative and revolutionary new ETABS is the ultimate integrated software package for the structural analysis and design of buildings. Incorporating 40 years of continuous research and development, this latest ETABS offers unmatched 3D object based modeling and visualization tools, blazingly fast linear and nonlinear analytical power, sophisticated and comprehensive design capabilities for a wide-range of materials, and insightful graphic displays, reports, and schematic drawings that allow users to quickly and easily decipher and understand analysis and design results.
From the start of design conception through the production of schematic drawings, ETABS integrates every aspect of the engineering design process. Creation of models has never been easier - intuitive drawing commands allow for the rapid generation of floor and elevation framing. CAD drawings can be converted directly into ETABS models or used as templates onto which ETABS objects may be overlaid. The state-of-the-art SAPFire 64-bit solver allows extremely large and complex models to be rapidly analyzed, and supports nonlinear modeling techniques such as construction sequencing and time effects (e.g., creep and shrinkage).

ETABS now utilizes cloud licensing, allowing access to the license by multiple users and/or from multiple machines. Cloud licensing normally requires connection to the internet while using the software, either directly or through a proxy. Licenses can be checked out for a limited time period to allow use while disconnected from the internet.
