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.
With the introduction of the standard ACI 318-19, the long-term relationships for the determination of the shear resistance of the concrete Vc were redefined. With the new method, the component height, the longitudinal reinforcement ratio, and the normal stress now influence the shear strength Vc. In the following, the changes in the shear design are described in detail and the application is shown by an example.
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.
The National Building Code of Canada (NBC) 2015 Article 220.127.116.11 provides a clear procedure for earthquake methods of analysis. The more advanced method, the Dynamic Analysis Procedure in Article 18.104.22.168, should be used for all structure types except those that meet the criteria set forth in 22.214.171.124. The more simplistic method, the Equivalent Static Force Procedure (ESFP) in Article 126.96.36.199, can be used for all other structures.
This article explains the equation solver for a nonlinear calculation with a Newton-Raphson iteration.
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.
In this article, images of a blast scenario of a remote detonation in RF-DYNAM Pro - Forced Vibrations are displayed and the effects are compared in the linear time history analysis.
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.
Computer technology has a firm grip on digital structural analysis and design. With each new development, the involved planners are able to push the limits of what is feasible upwards.
This article describes the basic principles and modeling approaches of pulley systems in RFEM.
