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.
Precast prestressed hollow core slabs consist of composite, uniaxially stressed non‑solid slabs with a width of about 1.20 m. These elements are prestressed with pre-tension in a precast concrete plant. The precasting is usually done with slipformers. Due to the lesser self‑weight of the non‑solid slab and the existing prestress, these precast prestressed hollow core slabs show a lesser deflection than loosly reinforced slabs made of solid concrete.
Until now, the load type prestress has always been an initial prestress in the Dlubal Software programs. The defined load magnitude was applied and, depending on the stiffness of the surrounding system, the prestress remained more or less as axial force in the cable.
In RFEM 5 and RSTAB 8, it is now possible to move or copy structures or structural components in a user-defined coordinate system.
If you want to orient a nodal support to the member axes of the connecting member, the easiest way to do this is to use the function ‘Pick Member and Import its Rotation’. This function can be found in the ‘Edit Nodal Support’ dialog box and must be specified for each axis individually.
In RFEM 5, you have the option to use the stiffness property (no tension) of surfaces to exclude the consideration of tensile forces in the principal directions (sigma 1 and sigma 2) in the model. By comparing this with an analytical model of a cracked tension zone, you see that now only compressive forces are active in the model and it is possible to simulate a crack.
For RFEM 5 and RSTAB 8, the cross‑section optimization in the add‑on modules was further improved. Now it is possible to optimize a cross‑section with regard to the according cross‑section table or a user‑defined cross‑section group. The relevant criterion is the cross‑section area.
In the world of construction engineering, the word ‘imperfections’ has a specific meaning. It describes the imperfections of a structure or the deviation of a structural component from its ideal form due to manufacturing.
The ‘Filter’ option in the cross‑section library allows you to show only cross‑sections of certain standards, shapes, or types. In the same window, you can also select the material.
In RFEM 5, new options for nodal and surface supports have been implemented. In addition to the already available options of support failure, RFEM 5 now offers features like nodal friction or nonlinear relations like support slippage as well as many other options. In the area of the surface supports, it is now possible to define them directly as rigid supports.
RF-/FOUNDATION Pro allows you to check the allowable eccentricity of the resultant of the bearing pressure. According to DIN EN 1997‑1/NA, this design is to be carried out with the characteristic or representative loads.
