Behavior of cold-formed steel wall panels under monotonic horizontal loading

This paper summarizes the findings of an experimental study on cold-formed steel (CFS) wall panels with oriented strand board (OSB) sheathing. Static lateral load tests were conducted on a total of thirteen full-scale wall panel specimens to investigate the performance of CFS walls utilizing primarily the construction details used in Turkey. Experimental results revealed that the geometry of hold-down attachment used at the base of CFS wall panels to transfer tensile forces has a major effect on the overall behavior of the panels. Extensive damage was observed to occur in the hold-down attachment and in part of the bottom track adjacent to the hold-down, which prevented the wall panels to exhibit the stiffness associated with the main load resisting mechanisms. Tilting of the screws connecting the OSB sheathing to the CFS boundary framing members, as well as the separation of sheathing from the framing members were other commonly observed deformation modes. Existence of diagonal struts inside CFS frame was determined to cause a slight increase in load capacity and initial stiffness of the panels. It is also shown that the measured load capacity of wall panels can be predicted with an acceptable accuracy using design equations available in the literature.


Behavior of steel-concrete partially composite beams with channel type shear connectors
Baran, Eray; Topkaya, Cem (2014-06-01)
This paper summarizes the findings of an experimental study investigating the flexural behavior of partially composite beams incorporating channel type shear connectors. Results from monotonic load testing of four full-scale steel-concrete composite beams and a steel beam are presented. The main effort focused on identifying the variation of strength and stiffness properties of beams with various degrees of partial composite action. Behavior of channel shear connectors in the composite beam specimens is rel...
Performance of seismic-isolated bridges in relation to near-fault ground-motion and isolator characteristics
Dicleli, Murat (SAGE Publications, 2006-11-01)
This paper investigates the performance of seismic-Isolated bridges (SIBs) subjected to near-fault (NF) earthquakes with forward rupture directivity effect (FRDE) in relation to the isolator, substructure, and NF earthquake properties, and examines some critical design clauses in AASHTO's Guide Specifications for Seismic Isolation Design. It is found that the SIB response is a function of the number of velocity pulses, magnitude of the NF ground motion, and distance from the fault. Particularly, a reasonabl...
Effect of out-of-plane behavior on seismic fragility of masonry buildings in Turkey
Ceran, Hasan Burak; Erberik, Murat Altuğ (Springer Science and Business Media LLC, 2013-10-01)
This study focuses on the evaluation of seismic safety of unreinforced masonry buildings in Turkey by using fragility curves generated for two behavior modes of load bearing walls: in-plane and out-of-plane. During generation of fragility curves, a force-based approach has been used. There exist two limit states in terms of base shear strength for in-plane behavior mode and flexural strength for out-of-plane behavior mode. To assess the seismic vulnerability of unreinforced masonry buildings in Turkey, frag...
Effects of cast-in-place concrete topping on flexural response of precast concrete hollow-core slabs
Baran, Eray (2015-09-01)
Results of a study focusing on the flexural response of precast prestressed concrete hollow-core slabs with cast-in-place concrete topping are presented. The experimental part of the study included load testing of five precast concrete hollow-core units. The numerically determined flexural response of test specimens was later compared with the experimentally obtained behavior. Results demonstrate that a major composite action is valid between the hollow-core unit and the topping slab under load levels corre...
Characterization of gas-solid flow in conical spouted beds operating with heavy particles
Sari, Salih; Külah, Görkem; KÖKSAL, MURAT (2012-07-01)
This study presents the results of an experimental investigation of the hydrodynamics of conical spouted beds operating with high density particles. This type of spouted beds is frequently encountered in chemical vapor deposition coating of nuclear fuel elements. Measurements were performed in three 15 cm ID full circular (gamma = 30 degrees, 45 degrees, 60 degrees) and one half circular conical spouted (gamma = 30 degrees) bed with yttria-stabilized zirconia particles (d(p) = 0.5, 1 mm; rho(p) = 6050 kg/m(...
