Effects of Floor System on Progressive Collapse Behavior of RC Frame Sub-Assemblages

open access: yesBuildings, 2022
The ability to predict the resistance of reinforced concrete (RC) structures to progressive collapse as a result of an interior column removal has become a need in structural design.

Factorization theory: From commutative to noncommutative settings [PDF]

open access: yes, 2015
We study the non-uniqueness of factorizations of non zero-divisors into atoms (irreducibles) in noncommutative rings. To do so, we extend concepts from the commutative theory of non-unique factorizations to a noncommutative setting.

Analytical Simplify Models Of The Key Elements In The Alternative Load Path Within The Frame In Accidental Situation

open access: yesTransactions of the VŠB: Technical University of Ostrava, Civil Engineering Series, 2015
The present document is dedicated to global behavior of a frame further to the loss of a column, taking into account the redistribution of the internal forces. Structural elements, transfer the load to the foundation, are isolated as key elements.

Research on Catenary Action of Frame Structure in Progressive Collapse with Fiber Model [PDF]

open access: yesAdvances in Computer Science Research, 2015
An advanced finite element model (FEM) is presented with fiber beam-column element of OpenSees in this study. Using this FEM, non-linear static push-down analysis of a steel frame structure was carried out by the alternate load path method, with two different cases that two different columns are removed respectively.

Design of an Over-Actuated Hexacopter Tilt-Rotor for Landing and Coupling in Power Transmission Lines

open access: yesDrones, 2023
It is known that new power transmission line inspection techniques have been developed over the last few years with great potential to improve and, in some cases, even replace traditional inspection procedures such as using helicopters and cars. A series

Experimental Tests of Steel Unstiffened Double Side Joints with Flush and Extended End Plate

open access: yesArchives of Civil Engineering, 2019
Experimental tests of steel unstiffened double side bolted end-plate joints have been presented. The main aim of the conducted tests was to check the behavior of joints in an accidental situation and possibility of creating secondary mechanism, i.e ...

Center Vortices, Area Law and the Catenary Solution

open access: yes, 2015
We present meson-meson (Wilson loop) correlators in Z(2) center vortex models for the infrared sector of Yang-Mills theory, i.e., a hypercubic lattice model of random vortex surfaces and a continuous 2+1 dimensional model of random vortex lines.

MECHANICAL BEHAVIOR AND CATENARY ACTION OF RESTRAINED STEEL BEAM UNDER FIRE [PDF]

open access: yes, 2021
To investigate the mechanical behavior and catenary action of restrained steel beam under fire, experiments were performed on five H-section restrained steel beams exposed to ISO-834 standard fire. At first, mechanical property tensile tests were performed on 3 room-temperature specimens and 8 high-temperature specimens, and variation laws of the ...

Progressive Collapse Resistance of Steel Frames with Reduced Beam Sections and Web Openings

open access: yesBuildings
Progressive collapse represents a critical failure scenario in steel moment-resisting frames, especially when beam sections are intentionally weakened through flange cuts or web openings.

Experimental Investigation of Progressive Collapse of Prestressed Concrete Frames after the Loss of Middle Column

open access: yesAdvances in Civil Engineering, 2020
Accidental loads such as explosion and vehicle impact could lead to failure of one or several load-bearing members in the structures, which is likely to trigger disproportionate progressive collapse of overall structures.
