Module: 03

Topic: Research and Development of different type of structural system with wind simulation. 

Software: CSI SAP2000 and DUBAL RWIND

1.1 Braced Frame and Diagrid System 

Braced Frames have much better strength and stiffness Bracing is a much  effective than rigid joints at resisting racking deformation of the frame.

1.2 Tube System 

The tube is the name given to the systems where in order to  resist lateral loads (wind, seismic, etc.) a building is designed to act like a three-dimensional hollow tube.

1.3 Braced Tube System 

Also known as ‘Trussed Tube’ or ‘Exterior Diagonal-tube System’ utilized for greater heights, and allows larger spacing between  the columns.

1.4 Out trigger structure system 

The outrigger truss is a simple trusses spanning over the full height of that story and across the full width of building.

1.5 Diagrid Structure system 

The diagrid (a portmanteau of diagonal grid)  is a framework of diagonally intersecting  metal, concrete or wooden beams that is  used in the construction of buildings and  roofs.

1.6 Wind Test/Wind Simulation in DUBAL RWIND 

RWIND Simulation Case Setup  RWIND   Simulation software, developed by companies PC-PROGRESS and DLUBAL, was designed   as specialized tool for rapid CFD simulations of wind load on large  variety of structures. RWIND Simulation works as standalone software, or it can be directly connected with structural design software RFEM or RSTAB.  RWIND Simulation user   interface is super ease of use with minimal    necessary settings and   user skills. The   work flow is very simple.  The input for RWIND    Simulation is the   surface model of the    structure(CAD,.STL).   The virtual wind tunnel    is created around the    structure. Wind speed is    set. There st of the     parameters are not mandatory, but available.

• Low Rise RCC Structure
• High Rise RCC Structure
• Tall Structure
• Tube Structure
• Iconic Structure
