Dynamic Behavior of Precast Concrete Beam-Column Sub-Assemblages with High Performance Connections Subjected to Sudden Column Removal Scenario [PDF]

open access: yes, 2020
Unbonded posttensioned precast concrete (UPPC) structure has shown its excellent aseismic performance in laboratory tests and earthquake investigation.

Experimental study and numerical analysis of progressive collapse resistance of composite frames [PDF]

open access: yes, 2013
A partial damage caused by an abnormal load could trigger progressive collapse of high rise buildings which may lead to terrible casualties. However, in the process of column failure, "catenary action" plays an important role in redistributing the ...

Assessment of the worthwhileness of efficient driving in railway systems with high-receptivity power supplies [PDF]

open access: yes, 2020
Eco-driving is one of the most important strategies for significantly reducing the energy consumption of railways with low investments. It consists of designing a way of driving a train to fulfil a target running time, consuming the minimum amount of ...

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.

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

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.

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 ...

Explicit formulas for a continuous stochastic maturation model. Application to anticancer drug pharmacokinetics/pharmacodynamics [PDF]

open access: yes, 2008
We present a continuous time model of maturation and survival, obtained as the limit of a compartmental evolution model when the number of compartments tends to infinity.

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.
