WebMar 15, 2024 · It is therefore desired that both the maximum interstory drift and the maximum acceleration exhibit an acceptable value with appropriate compromise. The double impulse as a simplified version of one-cycle sine wave as a representative of the main part of near-fault ground motions can simulate the maximum interstory drifts properly. WebInterstory drift, the relative translational displacement between two consecutive floors, is an important engineering demand parameter and indicator of structural performance.

A Method of Interstory Drift Monitoring Using a Smartphone and …
WebIn multi-storey construction, the effect often measured between storeys is called inter-storey drift . If the drift is too great and the components of the building envelope are rigidly fixed to the frame, damage can occur. Brittle elements such as windows can shatter, service pipes may rupture at joints and claddings may sustain damage. The ... WebAccordingly, superposing the additional shear interstory drift and the additional overall bending interstory drift, the additional interstory drift can be written as D j ¼ D M j þ D … WebThe interstory drift index is defined as interstory displacement, δs,i, divided by story height, hi. Thus, it defines the average rotation angle each beam-column subassembly in … figurines goodies lyon
