In the current validation example, we investigate wind pressure coefficient (Cp) for both main structural members (Cp,ave) and secondary structural members such as cladding or façade systems (Cp,local) based on NBC 2020 [1] and
Japanese Wind Tunnel Data Base
for low-rise building with 45 degree slope. The recommended setting for three-dimensional flat roof with sharp eaves will be described in the next part.
In the current validation example, we investigate wind pressure value for both general structural design (Cp,10) and local structural design such as cladding or façade systems (Cp,1) based on EN 1991-1-4 flat roof example [1] and
Japanese Wind Tunnel Data Base
. The recommended setting for three-dimensional flat roof with sharp eaves will be described in the next part.
In the current validation example, we investigate wind pressure coefficient (Cp) of flat roof and walls with ASCE7-22 [1]. In the section 28.3 (Wind loads - main wind force resisting system) and Figure 28.3-1 (load case 1), there is a table which shows Cp value for different roof angle.
The Architectural Institute of Japan (AIJ) has presented a number of well-known benchmark scenarios of wind simulation. The following article deals with "Case E - Building Complex in Actual Urban Area with Dense Concentration of Low-Rise Buildings in Niigata City". In the following, the described scenario is simulated in RWIND& 2 and the results are compared with the simulated and experimental results by AIJ.
In the current validation example, we investigate wind pressure value for both general structural designs (Cp,10) and cladding or façade design (Cp,1) of rectangular plan buildings with EN 1991-1-4 [1]. There are three dimensional cases that we will explain more about if in the next part.
Das Architectural Institute of Japan (AIJ) hat eine Reihe an bekannten Benchmark-Szenarien für Windsimulation vorgestellt. Der Nachfolgende Beitrag dreht sich dabei um den "Case A - high-rise building with a 2:1:1 shape". Im Folgenden wird das beschriebene Szenario in RWIND2 nachgebildet und die Ergebnisse mit den simulierten und der experimentellen Resultate des AIJ verglichen.
The Architectural Institute of Japan (AIJ) has presented a number of well-known benchmark scenarios of wind simulation. The following article deals with "Case D - High-Rise Building Among City Blocks". In the following, the described scenario is simulated in RWIND 2 and the results are compared with the simulated and experimental results by the AIJ.
In the current validation example, we investigate wind force coefficient (Cf) of cube shapes with EN 1991-1-4 [1]. There are three dimensional cases that we will explain more about if in the next part.
The verification example describes wind loads in several wind directions on a model of a group of buildings. The model consists of eight cubes. The velocity fields obtained by the RWIND simulation are compared with the measured values from the experiment. The experimental data are measured using a thermistor anemometer in the wind tunnel.
The verification example describes pressure loads on the walls of buildings in tandem arrangement located at ground level. The buildings are simplified to rectangular objects and scaled down while maintaining the elevation ratios. The pressure distribution on the walls of the model of a medium-high building was conducted by an experiment. The chosen results (pressure coefficient Cp) are compared with the measured values.
This verification example compares wind load calculations on a flat roof building using the ASCE 7-16 standard and using CFD simulation in RWIND Simulation. The building is defined according to the sketch and the inflow velocity profile taken from the ASCE 7-16 standard.
