Design factor that reduces wind resistance
WebSep 26, 2024 · The behavior of a very slender building is investigated under wind loads, to satisfy both strength and serviceability (comfort) design criteria. To evaluate the wind effects, wind tunnel testing and structural analysis were conducted, by two different procedures: (i) Pressure Integration Method (PIM), with finite element modeling, and (ii) … WebIn particular you get energy losses due to plastic deformation in the surfaces that are sliding over each other, and this manifests as a frictional force i.e. the energy loss means you need to do work to slide the surfaces.
