Effect of drift on gravity columns
WebThe point loads represent the notional load effect on each col-umn. By applying the loads to all columns and including all framing in the model, the effect of leaning columns is directly included as part of the analysis. This method correctly distributes the notional loads in the same manner as the total factored gravity load and WebNov 20, 2024 · 1) The naturally occurring slab / column moment connections that Celt mentioned. 2) The primary issue of concern in CIP systems is punching shear failure at …

WebApr 21, 2009 · The likely effects of secondary moments due to the gravity load, which is being laterally displaced during inelastic seismic storey drift, upon ductile reinforced concrete frames is examined. WebDec 1, 2024 · In order to measure the effects of connection fixity and gravity framing on drift concentration tendency, a drift concentration factor (DCF) was considered, defined as the ratio of maximum storey drift to the maximum roof drift [19]. Values of DCF much greater than unity indicate that drift is not distributed evenly over the building height.
