Combination Rules

Dynamic wind loads on tall buildings can be decomposed into three components, i.e. two translational components and one torsional component. When one component reaches its maximum, the other two components have low probability to take their maximum values. It is common to use combination coefficients for estimating the mean extremes of linearly combined wind loads. The traditional design practice for determining wind load combinations relies partly on some approximate combination rules and lacks a systematic and reliable method. Based on the high frequency force balance (HFFB) testing results, wind loads can be acquired in terms of time history data, which provides necessary information for the more rigorous determination of combination coefficients by probabilistic methods. In this paper, a 3D copula-based approach is proposed for determining the combination coefficients for three stochastic wind loads associated with a specific exceedance probability and a set of 3D realizable equivalent static wind loads (ESWLs) on tall buildings. Using the measured base moment and torque data by the HFFB wind tunnel test, a case study is presented to illustrate the effectiveness of the proposed framework to determine the dynamic wind load combinations and associated 3D realizable ESWLs on a full-scale 60-story building.

Wind Induced Vibration

The responses of tall buildings under wind loads in hilly terrain are remarkably different from that in flat terrain. Wind load codes can’t work efficiently or directly to calculate the wind-induced vibration of tall buildings in hilly terrain. Utilizing some wind tunnel test results of wind field in hilly terrain and pressures on tall buildings, the access to response of tall buildings on hilly terrain were provided. Some effects from hill characteristics to building responses were discussed.

<p>Kruunuvuori Bridge is new link to connect Laajasalo area to the Helsinki city center by crossing a Kruunuvuorenselkä bay. It’s a cable stayed bridge with a single pylon and symmetric span arrangement, designed to be built with free cantilever method. For such a structure, wind is a governing load for the construction and for the final stage.</p><p>In the Engineering design of the bridge, equivalent static wind load (ESWL) extraction was used to define the action forces for the structures due to the wind. With the applied method it is possible to include crucial frequency-dependent parameters like statistical wind turbulence parameters; aerodynamic damping; aerodynamic admittances and modal coupling into the design. Skew wind angles could also be defined. Such loads are easy to apply with general commercial software and the workflow for the design is practical. As the method itself is not standardized and includes specialist defined parameters, it requires an additional verification. This paper describes how the static equivalent wind loads were applied in the design and how the results were verified with full-aeroelastic model wind tunnel testing. As a conclusion, static wind load extraction provides reliable results and is a practical approach for bridge design under skew winds.</p>
