This study accurately determines the base overturning moments as well the equivalent static point load distributions and shear force distributions over the height of the tower building. A typical report also includes maximum building displacements along the various axes of the tower and the assessment of occupant comfort based on the measured levels of tip accelerations. Rotational velocities are also checked as they tend to affect occupant comfort from the point of view of visual cues. The building accelerations and rotational velocities are compared against a range of comfort criteria. Where the criteria are exceeded, WINDTECH Consultants can design suitable tuned mass dampers or tuned liquid dampers to control the building motion to an acceptable level.

WINDTECH Consultants’ modal analysis technique, used in the analysis of wind loads on tall buildings represents current world best practice. This technique provides the most accurate approach to the analysis of wind tunnel data, particularly for complex structures or buildings having highly coupled modes of vibration between the two translational modes and the torsional mode. Our standard scope also includes the prediction of the correlation between different modes of vibration, which is particularly important when the natural frequencies of these modes are very close.
WINDTECH Consultants has also devised an advanced methodology for accurately determining the load distribution on linked tall buildings and dynamic structures from wind tunnel data. This effectively overcomes any limitation due to complexity of the dynamic behaviour of the structure being investigated.

Besides determining the Base Moments, Equivalent Static Point Load Distributions, Shear Force Diagrams, a typical report includes maximum building displacements for each of the degrees of freedom for each tower and the assessment of occupant comfort based on the measured levels of tip accelerations and comparisons with respect to different occupant comfort criteria. Accelerations are presented for three levels of damping. In addition to accelerations, which reflect the physiological effect of the building motion on the occupants, the peak rotational velocity is also determined. This parameter is important in assessing the potential for alarm due to the building motion by means of visual cues. The results are compared against the Isuymov criterion.
