Evaluation of the out-of-plane behavior of stud-to-track connections in nonstructural partition walls

Abstract

A series of component-level experiments have been performed aiming to characterize the out-of-plane force-displacement response and damage mechanisms of stud-to-track connections in nonstructural steel-framed partition walls. The performance of connections with various stud-to-track gap dimensions, stud and track thicknesses, and screw-attachment configurations were evaluated and compared. In addition, the accuracy of available design provisions for estimating the ultimate connection capacity was assessed. The experimental data was then used to generate capacity fragility curves in terms of displacement and force. Finally, a series of nonlinear numerical hinge models were developed and calibrated that represent the out-of-plane hysteresis behavior of stud-to-track connections.

Fragility Comprehensive Assessment of Low‐Rise Cold‐Formed Steel Framed Wall Structure Subjected to Wind Load

“…To calculate the structural response to wind, considering the randomness of the wind load input and the structural response, the wind load is divided into six 10-minute mean wind speed levels (20,30,40,50,60, and 70 m/s). Using the Davenport spectrum [36] as given in equations ( 6) and ( 7), the fluctuating wind speed time history is obtained by equation ( 8) based on the harmonic superposition method [37].…”

“…e CFS framing walls are not only part of the main structure but also an important cladding component. When the walls are considered as a cladding component, their out-of-plane load-bearing performance is of primary concern [20,21]. e roof sheathing consists of roof trusses, purlins, and roof panels, with the roof panels and purlins typically bolted together.…”

Lightweight Steel Constructions for Seismic Areas

“…Main studies can by grouped in cyclic tests [70][71][72][73][74][75][76][77], and shake table tests [78,79] of partitions; shake table tests of suspended ceiling [80,81], and shake table tests of systems made of partitions and suspended ceiling [82,83]. In addition, also specific activities for the experimental evaluation of mechanical properties of cladding boards [84] and connections [85] were carried out.…”

Seismic Fragility of Chinese Light‐Gauge Steel Keel Gypsum Board Partition Walls

“…Quasi-static tests were performed with a varying number of dampers, showing that the ultimate bearing capacity of the wall with dampers was greatly increased. Rahmanishamsi et al conducted monotonic loading tests and hysteretic tests to study the performance of LSKGBPWs [18][19][20][21], including 31 gypsum board steel stud connection specimens, 33 steel stud-track connection specimens, and 22 track-floor connection specimens. In addition, a series of nonlinear plasticity models of partition wall joints were developed in OpenSees for numerical analysis of the wall.…”
