Dynamic Response of Tall Buildings

Aerodynamic Admittance Function of Tall Buildings

The aerodynamic admittance function (AAF) has been widely invoked to relate wind pressures on building surfaces to the oncoming wind velocity. In current practice, strip and quasi-steady theories are generally employed in formulating wind effects in the along-wind direction. These theories permit the representation of the wind pressures on building surfaces in terms of the oncoming wind velocit...

Estimating Fundamental Frequencies of Tall Buildings

Empirical estimates of the fundamental frequency of tall buildings vary inversely with their height, a dependency not exhibited by the various familiar models of beam behavior. This paper examines and explains this apparent discrepancy by analyzing the consequences of using two models to estimate such natural frequencies: A two-beam model that couples the bending of a classical cantilever to th...

Design of Tall Buildings – Preliminary Design

The design of tall buildings essentially involves a conceptual design, approximate analysis, preliminary design and optimization, to safely carry gravity and lateral loads. The design criteria are, strength, serviceability, stability and human comfort. The strength is satisfied by limit stresses, while serviceability is satisfied by drift limits in the range of H/500 to H/1000. Stability is sat...

Experimental Verification and Full-Scale Deployment of Global Positioning Systems to Monitor the Dynamic Response of Tall Buildings

The Civil Engineering community has long needed methods of accurate global displacement measurement for use in construction and more recently in the areas of structural health monitoring. Global Positioning Systems GPS provide one answer to this challenge, with rapid advancements in the available sampling rates and tracking resolution. However, as a relatively new dynamic sensing technology, GP...
