Using ASCE 7-22 for wind load calculations in RFEM and RWIND involves several specific steps to ensure that your structural designs meet the latest standards provided by the American Society of Civil Engineers. Here’s a step-by-step guide on how to incorporate ASCE 7-22 wind load provisions into RFEM and RWIND simulations:
Given that realistic determination of the soil conditions significantly influences the quality of the structural analysis of buildings, the Geotechnical Analysis add-on is offered in RFEM 6 to determine the soil body to be analyzed.
The way to provide data obtained from field tests in the add-on and use the properties from soil samples to determine the soil massifs of interest was discussed in Knowledge Base article “Creation of the Soil Body from Soil Samples in RFEM 6”. This article, on the other hand, will discuss the procedure to calculate settlements and soil pressures for a reinforced concrete building.
With the release of the structural analysis programs RFEM 6, RSTAB 9, RSECTION 1, and RWIND 2, Dlubal Software introduces a new generation of structural analysis programs. True to the motto "Structural analysis that is fun ...", the program provides users with universal tools with which they can meet all the requirements in structural engineering. Find out more about the latest developments at Dlubal Software in this article.
The new generation of RFEM software is an intuitive, powerful, and easy-to-handle 3D FEA program that meets all the latest demands in modeling, calculation, and structural design. The modern design concept, as well as the introduction of new features, make the program even more innovative and user-friendly. The main differences between RFEM 6 and its previous version, RFEM 5, are discussed in the following text.
The Aluminum Design Manual (ADM) 2020 was released in February 2020. The ADM 2020 gives guidance for both the allowable strength design (ASD) and load and resistance factor design (LRFD) for aluminum members to ensure reliability and safety for all aluminum structures. This latest standard was integrated in the RFEM/RSTAB add-on module RF-/ALUMINUM ADM. The text below will highlight the applicable updates relevant to the Dlubal programs.
The function, which is also known as shifting, allows you to calculate critical load factors beyond a user‑defined initial value. Determination of the critical load factors is usually done from the smallest to the greatest critical load factor.
The building and construction industry is increasingly digitized. Structural engineers, a smaller group in the construction industry, are not always considered to be engineers who follow the latest trends immediately. There is often good reason for this. Many consider this to be the reason that topics such as utilizing the BIM method are not yet the standard in structural engineering. However, the past few years have shown that a process of rethinking has begun, and new digital trends are being picked up and applied.
The boundary conditions of a plate support can be entered quickly as singular and line supports in the FEA software. However, if the flexibility of the supports is not considered when modeling the structure, it is often necessary to take a closer look at the support definitions during the design using stresses or the determination of the required reinforcement, at the latest.
In the latest version of RFEM, nodal constraints were implemented. Therefore, you can now connect the nodes in an ideal way. The diaphragm type represents the option to couple nodes in a plane. This option is available not only for the global coordinate system, but also for user-defined coordinate systems.
With the latest version of RF‑/DYNAM Pro, you can exclude the mode shapes from the seismic design. In most standards, there are provisions to exclude the effective modal mass factors that are too small. The "Mode Shapes" tab offers the option to specify the factor and to disregard the mode shapes automatically.
With the latest version of CONCRETE and RF-CONCRETE Members, it is possible to perform shear design for the connection of compression and tension flanges on a T-beam web.
