Hyperbolicity and fundamental groups of complex quasi‐projective varieties (III): Applications

open access: yesProceedings of the London Mathematical Society, Volume 133, Issue 5, November 2026.
Abstract This paper is Part III of a series of three. We begin by introducing the notion of h$h$‐special varieties, which can be seen as varieties “chain‐connected by the Zariski closures of entire curves.” We prove that if X$X$ is either a special smooth complex quasi‐projective variety in the sense of Campana or an h$h$‐special variety, then for any ...

3D Fiber-Based Frame Element with Multiaxial Stress Interaction for RC Structures

open access: yesAdvances in Civil Engineering, 2018
A three-dimensional fiber-based frame element accounting for multiaxial stress conditions in reinforced concrete structures is presented. The element formulation relies on the classical Timoshenko beam theory combined with sectional fiber discretization ...

Torsional Resistance of High Strength Concrete Filled Steel Tube Beams Stiffened Internally with Steel Bars

open access: yesTikrit Journal of Engineering Sciences
The torsional behavior of twelve concrete-filled steel tube (CFST) specimens was experimentally investigated. CFST specimens were reinforced by internal cross-rods with different spacing (0, 50, 100, 150, 200, and 250) mm, different thicknesses of the ...

Experiment on Torsional Behaviour of Reinforced Concrete Beams

open access: yesInternational Journal of Innovative Technology and Exploring Engineering, 2019
Structural beams in construction are subjected to significant torsional moment which affects the design of structures.Eight beams were produced with two distinct grade of concrete with two ratios of longitudinal as well as transverse reinforcements.An experiment for evaluation of torsional strength of reinforced concrete beams is presented in this ...

Lateral-torsional buckling resistance of pultruded fibre reinforced polymer shapes [PDF]

open access: yes
The currently lack of design guidance for pultruded fibre-reinforced polymer member requires more study on their structural behaviours in order to provide structural designer with confidence when applying this material into civil engineering.
