Why Dlubal Software?
Wind Simulation & Wind Load Generation
With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.

Shear Resistance Vc According to ACI 318-19
With the most recent ACI 318-19 standard, the long-term relationship to determine the concrete shear resistance, Vc, are redefined. With the new method, the member height, the longitudinal reinforcement ratio, and the normal stress now influence the shear strength, Vc. The following article describes the shear design updates, and the application is demonstrated with an example.

Modeling of a glass railing | Tips for entering data in RFEM
The architectural requirements for railings are still very high and usually require a high degree of transparency. Glass railings, where no other frame structure can be seen, represent an option for implementation.

NBC 2015 Modal Response Spectrum Analysis and Base Shear Considerations
The National Building Code of Canada (NBC) 2015 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.

Notes on Considering Flush Beam Strips or Intermittent Ceiling Supports in Reinforced Concrete Structures
According to Book 631 of the DAfStb (German Committee for Structural Concrete), Chapter 2.4, the structural behavior of ceilings changes if their continuous support by walls is interrupted in areas of openings. Depending on the length of the opening area and the plate thickness, measures are necessary regarding the analysis of the ceiling in the area of the opening.

Reduction of shear force Vz for the design in RF-CONCRETE Members and CONCRETE according to EN 1992-1-1
For shear force design in RF-CONCRETE Members and CONCRETE, the acting shear force Vz can be reduced according to EN 1992-1-1. The following article describes the reduction of the concentrated loads close to the support and the shear force design at a distance d from the support edge for a uniform load.

Updating and aligning structural data across models using the COM interface
For some structures, it is necessary to design them in different configurations. Thus, it may be the case that a lifting platform must be analyzed in the position on the ground, in the middle and extended. Since such tasks require the creation of several models, but they are almost identical, updating all models with just one mouse click makes the work considerably easier.
