Operation of pre-stressed span beams of bridge cranes taking into account load combinations

open access: yesTrudy Odesskogo Politehničeskogo Universiteta, 2022
The paper considers issues related to increasing the bearing capacity of span beams of bridge cranes by means of pre-stressing. It is known that the work of the span structure of the crane with pre-stressed beams takes place under the same conditions ...

Experimental Research on the Instantaneous and Long-Term Deflections of Pre-Cracked Concrete Beams Enhanced by Carbon Fibre Reinforced Polymer [PDF]

open access: yesFracture and Structural Integrity, 2018
This paper aims to disclose the influence law of cracks on instantaneous and long-term deflections of reinforced beam. For this purpose, four concrete beams were created, pre-loaded to varied degrees of cracking, and reinforced with carbon fibre ...

Multiple Time-Scales Analysis to Predict the Quasiperiodic Oscillatory Response of a Thin-Walled Beam Subjected to 1:1:1 Simultaneous Resonance

open access: yesShock and Vibration, 2023
This paper introduces a study on the horizontal and vertical deflections of the cross section of a thin-walled rotating beam. These deflections are governed by a system of two ordinary differential equations in order to describe their Cartesian ...

Maximum Stress Estimation Model for Multi-Span Waler Beams with Deflections at the Supports Using Average Strains

open access: yesSensors, 2015
The safety of a multi-span waler beam subjected simultaneously to a distributed load and deflections at its supports can be secured by limiting the maximum stress of the beam to a specific value to prevent the beam from reaching a limit state for failure

Bending Behavior and Deflection Prediction of High-Strength SFRC Beams under Fatigue Loading

open access: yesJournal of Materials Research and Technology, 2020
The experiments of high-strength steel-fiber-reinforced concrete (SFRC) beams subjected to fatigue bend loading were conducted in this work. A total of 12 beams were tested to failure, including 2 under static loading and 10 under fatigue loading.

Capturing functional relations in fluid–structure interaction via machine learning

open access: yesRoyal Society Open Science, 2022
While fluid–structure interaction (FSI) problems are ubiquitous in various applications from cell biology to aerodynamics, they involve huge computational overhead. In this paper, we adopt a machine learning (ML)-based strategy to bypass the detailed FSI

Mechanical behavior of 2D FGP beam with uneven porosity distribution

open access: yesJournal of Architectural and Engineering Research, 2023
This study gives the mechanical behavior of 2D functionally graded porous (FGP) beams using the finite element method. The Matlab code with simple Timoshenko beam elements is written to solve 2D FGP beam problems under distributed load.
