Wind tunnel simulation of TTU flow and building roof pressure
Abstract A study of approach wind flow and wind-induced pressure on a 1 : 50 geometrical scale model of the Texas Tech University test building was performed in a boundary layer wind tunnel at Colorado State University. The model and full-scale flow parameters and pressure coefficients are presented for low-turbulence nominal flow. The comparison of the model and prototype building point pressure exhibits a better agreement for most of the pressure taps, including the critical corner region, than other reported wind tunnel results. The study shows a significant reduction in the extreme peak pressure at critical locations due to low-pass filtering with a relatively high-frequency cut-off. This points out to the importance of proper selection of the frequency range for low-pass filtering and sampling of the pressure signals.
This paper researches on the design guidelines for Siemens gas turbine-generator foundation and ISO standard.Meanwhile,it takes a 9 F grade Siemens gas turbine-generator foundation in construction for example,some suggestions for the set of disturbance values of Siemens gas turbine-generator and the vibration control standard are proposed.
