Effect of Architectural Non-Structural Components on Lateral Behaviour of CFS Structures: Shake-Table Tests and Numerical Modelling

Abstract

This paper illustrates the effect of architectural non-structural components on the variation of dynamic properties and lateral seismic behaviour of Cold-Formed steel (CFS) buildings, using shake-table tests and numerical modelling. The seismic behaviour of a two-storey gypsum-sheathed building was investigated as a part of European project ELISSA. Shake-table tests were carried-out on this building under two different configurations: with and without architectural non-structural components. Dynamic properties, such as fundamental period and damping ratio, of both building configurations were evaluated and compared. Numerical models considering all the architectural non-structural components were developed in Opensees environment. Results highlight the importance of considering the contribution of architectural non-structural components, such as finishing materials of shear and gravity walls, partition walls and internal counter walls, in the process of structural analysis and modelling of CFS buildings.

Influence of the P-Delta Effect on the Design of Steel Moment Resisting Frame in Seismic Areas

“…Numerical analyses are a powerful tool in the investigation of the structural behavior; as indeed demonstrated by several studies [13][14][15][16][17][18][19][20], numerical investigation can accurately mimic experimental structural behavior. The modelling procedure introduces is in line with what was reported by the Authors [21,22] in previous research; therefore, hereinafter only the main information is reported.…”

Numerical Investigations on Dynamic Behaviour of Lumped Mass Model of Non-Structural Elements and 3d Rc Buildings

“…Particularly, the architectural NSEs triples the lateral stiffness of building and reduce inter-storey drift by more than 2 times. [2]. Failure of acceleration sensitive NSEs occurs frequently after an earthquake because the dynamic features of the supporting structure are disregarded while calculating the seismic demand on NSEs [3].…”

The Performance of Preloaded Bolts in Seismically Prequalified Steel Joints in a Fire Scenario

“…Steel structures are widely used in seismic areas since they guarantee ductile and dissipative behavior by means of localized plastic deformations [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ]. Among the wide range of structural typologies, moment resisting frames (MRFs) are the most ductile due to redundancy that guarantees plastic redistribution in plastic hinges at the beam ends.…”
