Overall Stability Behavior and Design Method of Q460 High Strength Steel Welded I-section Two-span Continuous Beam

open access: yesTaiyuan Ligong Daxue xuebao, 2021
In order to investigate the overall stability behavior of Q460 high strength steel welded I-section two-span continuous beam and develop the design method of such beams in codes, a finite element model considering residual stress was established by using

Stochastic analysis for bending capacity of precast prestressed concrete bridge piers using Monte-Carlo simulation and gradient boosted regression trees algorithm

open access: yesAdvances in Bridge Engineering, 2023
The use of precast prestressed concrete bridge piers is rapidly evolving and widely applied. Nevertheless, the probabilistic behavior of the bending performance of precast prestressed concrete bridge piers has often been overlooked.

Mathematical Investigation of 1D Discontinuity Waves in Dilute Granular Gases

open access: yesMathematics, 2023
The propagation of acceleration waves in dilute granular gases was investigated. Acceleration waves propagating in elastic gases, mixtures, and other materials are widely studied in the literature, but not in granular gases.

Study on bending strength of sandwich U-shaped beam with lattice core

open access: yesNihon Kikai Gakkai ronbunshu, 2022
In this paper, the bending collapse behavior of sandwich U-shaped beam with lattice core has been investigated by using finite element analysis. In particular, the effects of geometric properties of lattice core and faceplate on the maximum bending ...

Analysis of Dynamic Response and Ultimate Strength for Box Girder under Bending Moment

open access: yesJournal of Marine Science and Engineering, 2023
The box girder can be seen as a kind of simplified ship structure that can withstand a vertical bending moment. Dynamic loads play an important role in structural safety analysis, such as ship bow slamming during harsh sea conditions.

Closed-form critical response of elastic-plastic shear building with viscous damper under pseudo-double impulse for simulating resonant response under near-fault fling-step motion

open access: yesFrontiers in Built Environment, 2022
A set of approximate closed-form solutions of the maximum interstory drifts under the critical pseudo-double impulse (PDI) is derived for non-proportionally damped multi-story shear building models with bilinear hysteresis.

On the evaluation of elastic critical moments in doubly and singly symmetric I-section cantilevers [PDF]

open access: yesJournal of Constructional Steel Research, 2007
Abstract The so-called 3-factor formula is one of the most commonly employed general formulae to estimate the elastic critical moment of steel beams prone to lateral-torsional buckling. This work extends its domain of application to I-section cantilevers (i) with equal or unequal flanges, (ii) fully built-in or free to warp at the support and (iii ...

Web rotational stiffness of continuous steel-concrete composite castellated beams

open access: yesFracture and Structural Integrity, 2019
Continuous composite beams can present a global instability known as lateral distortional buckling (LDB). The design code EN 1994-1-1:2004 provides a procedure for the verification of this ultimate limit state, in which the resistant bending moment is ...

Lateral distortional buckling of cellular composite-beams

open access: yesRevista IBRACON de Estruturas e Materiais, 2018
In the region of negative bending moments of continuous and semi-continuous steel and concrete composite beams, the inferior portion of the steel section is subjected to compression while the top flange is restricted by the slab, which may cause a global

A new expression to predict secant rotational stiffness of spudcan in undrained soils [PDF]

open access: yesE3S Web of Conferences, 2021
The nonlinear behavior of spudcan foundation will lead to the decrease of the rotational stiffness of the spudcan, leading to the increase of the stress at the critical member of the offshore jack-up drilling platform. Secant rotational stiffness is used
