  1. Balanced and Unbalanced Snow Loads for Curved Roofs According to the ASCE 7-16

    The ASCE 7-16 standard requires both balanced and unbalanced snow load case scenarios for a structure's design consideration. While this may be more intuitive for flat or even gable/hip type roofs, the determination of snow loads is increasingly more difficult for arch roofs due to complex geometry. However, with guidance from the ASCE 7-16 on snow load calculations for curved roofs and RFEM's efficient load application tools, it's possible to consider both balanced and unbalanced snow loads for a reliable and safe structure design.

  2. Approximate Consideration of P-Delta Effects with Amplification Factors in RF-DYNAM Pro - Equivalent Loads

    P-Delta Effects and Seismic Design According to the ASCE 7-16 and NBC 2015

    As gravity loads act on a structure, lateral displacement occurs. In turn, a secondary overturning moment is generated as the gravity load continues to act on the elements in the laterally displaced position. This effect is also known as "P-Delta (Δ)." Sect. 12.9.1.6 of the ASCE 7-16 Standard and the NBC 2015 Commentary specify when P-Delta effects should be considered during a modal response spectrum analysis.

    Wind Loads on Circular Dome Roof Structures According to ASCE 7-16

    When it comes to wind loads on building type structures per the ASCE 7, numerous resources can be found to supplement design standards and aid engineers with this lateral load application.  However, engineers may find it more difficult to find similar resources for wind loading on non-building type structures.  This article will examine the steps to calculate and apply wind loads per the ASCE 7-16 on a circular reinforced concrete tank with a dome roof.

    Determination of Story Drift According to ASCE 7-16 Under Seismic Loads

    The story drift of a building provides valuable information about its structural behavior under seismic loads.
  5. Determination of the Maximum Horizontal and Vertical Loads to Calculate the Stability Coefficient

    Consideration of P-Delta Effects (Second-Order Analysis) in the Response Spectrum Analysis According to ASCE 7-16

    RFEM offers the option to perform a response spectrum analysis according to ASCE 7-16. This standard describes the determination of seismic loads for the US-American market. It might happen that the so-called P-Delta effect has to be considered due to the stiffness of the entire structure to be able to calculate the internal forces and carry out the design.

    Determination of Transversal Shear Under Seismic Loads

    In RF-/DYNAM Pro - Equivalent Loads, the equivalent seismic loads can be calculated according to different standards. By calculating the equivalent loads for each eigenvalue, it is not directly possible to obtain the transversal shear for each story to perform an analysis afterwards. The following example describes the option to calculate the transversal shear quickly and efficiently.

    Generating Wind Loads on Walls and Roofs According to ASCE/SEI 7-16

    RFEM and RSTAB allow you to easily consider wind load effects on a three-dimensional building according to ASCE/SEI 7‑16 [1]. This article explains the complex theory of entering wind loads in the software. You can find the wind load under “Tools” → “Generate Loads” → “From Wind Loads.”
