Knowledge Base Articles
KB 001877 | ASCE 7-22 and NBC 2020 Seismic P-Delta Considerations in RFEM 6
The ASCE 7-22 Standard [1], Sect. 12.9.1.6 specifies when P-delta effects should be considered when running a modal response spectrum analysis for seismic design. In the NBC 2020 [2], Sent. 4.1.8.3.8.c gives only a short requirement that sway effects due to the interaction of gravity loads with the deformed structure should be considered. Therefore, there may be situations where second-order effects, also known as P-delta, must be considered when carrying out a seismic analysis.
Modal Analysis | Steel Structure
This article presents the basic concepts in structural dynamics and their role in the seismic design of structures. Great emphasis is given to explaining the technical aspects in an understandable way, so that readers without deep technical knowledge can gain an insight into the subject.
KB 001875 | AISC 341-22 Moment Frame Member Design in RFEM 6
The three types of moment frames (Ordinary, Intermediate, Special) are available in the Steel Design add-on of RFEM 6. The seismic design result according to AISC 341-22 is categorized into two sections: member requirements and connection requirements.
KB 001860 | NBC 2020 Modal Response Spectrum Analysis and Base Shear Considerations in RFEM 6
The National Building Code of Canada (NBC) 2020 Article 4.1.8.7 provides a clear procedure for earthquake methods of analysis. The more advanced method, the Dynamic Analysis Procedure in Article 4.1.8.12, should be used for all structure types except those that meet the criteria set forth in 4.1.8.7. The more simplistic method, the Equivalent Static Force Procedure (ESFP) in Article 4.1.8.11, can be used for all other structures.

Product Features
Steel Design | Seismic Force-Resisting System Design Overview
  • Design of five types of seismic force-resisting systems (SFRS) includes Special Moment Frame (SMF), Intermediate Moment Frame (IMF), Ordinary Moment Frame (OMF), Ordinary Concentrically Braced Frame (OCBF), and Special Concentrically Braced Frame (SCBF)
  • Ductility check of the width-to thickness ratios for webs and flanges
  • Calculation of the required strength and stiffness for stability bracing of beams
  • Calculation of the maximum spacing for stability bracing of beams
  • Calculation of the required strength at hinge locations for stability bracing of beams
  • Calculation of the column required strength with the option to neglect all bending moments, shear, and torsion for overstrength limit state
  • Design check of column and brace slenderness ratios
Seismicity in Steel Design Add-on | Results

The seismic design result is categorized into two sections: member requirements and connection requirements.

The "Seismic Requirements" include the Required Flexural Strength and the Required Shear Strength of the beam-to-column connection for moment frames. They are listed in the ‘Moment Frame Connection by Member’ tab. For braced frames, the Required Connection Tensile Strength and the Required Connection Compressive Strength of the brace are listed in the ‘Brace Connection by Member’ tab.

The program provides the performed design checks in tables. The design check details clearly display the formulas and references to the standard.

Feature 002794 | "Dashpot" Member Type

Using the "Damper" member type, you can define a damping coefficient, a spring constant, and a mass. This member type extends the possibilities within the Time History Analysis.

With regard to viscoelasticity, the "Damper" member type is similar to the Kelvin-Voigt model, which consists of the damping element and an elastic spring (both connected in parallel).

Feature 002784 | Hinge Diagram

For calculation diagrams, you can use the "2D | Hinge" diagram type. These hinge diagrams show the hinge response of load situations for nonlinear hinges.

For calculations with several load situations, such as the case with the pushover analysis and time history analysis, you can evaluate the hinge condition in each load step.
