Vortex induced at High Rise Building

Wind load on high rise building are very complex, because of many aspects can effects the phenomenon. For instance: shape of the building, terrain around the building, vortex shedding, pressure fluctuation, etc. Wind flow around the building causes the building to oscillate, along wind, cross wind direction, and torsion. Then, vibration on high rise building... Continue Reading →

High Rise Building Vibration

Some of the causes of vibration that occurs in tall buildings. problems that most of us know is a vibration in buildings due to earthquake. but there are other causes that led to the building vibrate faster, this is caused by wind loads acting on the surface of the building.harmonic load due to wind can cause buildings to vibrate at a level of discomfort for the occupants of the building. many factors that affect the wind loading on tall buildings,including the shape of the building, the area where the building is in, and climate around the building. while the factors that affect a large vibration that occurs in the building except for the...

Vibration Measurement setup for Modal Testing

Soft suspense Soft suspense Charge & Conditioning amplifier for shaker Charge & Conditioning amplifier for accelerometer Shaker MSA/DSA Computer Accelerometer Power Amplifier  SG : Signal generator LC : load cell This setup is to measure Point FRF (Frequency Response Function) .  The excitation force provided by shaker and measured by a load cell that exist in the shaker and the vibration response will be read by the accelerometer (accelerometer sensor is used as to result in inertance and an...
