Shear performance evaluation of PHC piles under different levels of axial load ratio
Earthquake Engineering & Structural Dynamics, 2022 AbstractPrecast prestressed high‐strength spun concrete (PHC) piles are one of the common types of piles used in Japan due to its high bearing capacity. These piles have been utilized as an industrial standard since the 1970s as part of earthquake‐resilient foundation systems.

Influence of Axial Load Level on Performance of Resist Impact on Tubular T-Joint
Applied Mechanics and Materials, 2012 Axial load loading on the chord can deteriorate impact performance of tubular T-joint subjected to impact loading on the brace. FEA method was used in this paper to investigate the influence of different axial load level under varied impact energy. The analysis result showed that with the increasing of axial load level, the impact force decreased, and ...

Journal of Building Engineering, 2021 Abstract Ultra-high performance concrete (UHPC) is a new class of concrete materials that features high strength, ductility, and damage tolerance. This study experimentally evaluated three new UHPC jacketing strategies for retrofitting shear-deficient reinforced concrete (RC) columns, including cast-in-place UHPC jackets with or without steel bar ...

International Journal of Civil Engineering, 2021 This paper investigates experimentally the effect of elevated temperatures on the behavior of concrete columns, internally reinforced with longitudinal carbon fiber reinforced polymer (CFRP) bars. Eight columns were reinforced with steel and CFRP bars each, cast, and cured for 28 days before exposed to elevated temperatures of (200–400 °C).

Experimental Investigation on the Limitation of Axial Load Level of RC Columns in Seismic Regions
Advances in Structural Engineering, 2006 This paper presents an experimental study on the limitation of the axial load applied to reinforced concrete (RC) frame columns with circular, square and diamond sections. Based on seismic tests of 14 large-scale column specimens under low frequency cyclic lateral load, the failure pattern, the hysteresis effects, the skeleton curves, the energy ...

Computers & Structures, 2011 First, a finite element unit cell model of a glass fibre plain weave has been developed via an implicit subroutine. Because of the complex behaviour of fibrous yarns, a user-defined constitutive model needed to be defined. Material properties of yarns in the dry fabric are extracted by fitting the numerical model to experimental data under the uni ...

Journal of Engineering for Power, 1982 In axial-flow turbomachines considerable dynamic blade loads and noise production occur as a result of the unsteady blade row interaction between rotor and stator blades. This paper presents results of midspan measurements of the dynamic pressure distribution on the stator blade surface (fixed number of blades) for various rotor-blade numbers and ...

Clinics in Sports Medicine, 1987 The traumatic C3-C4 level injuries sustained by young athletes and documented by the National Football Head and Neck Injury Registry are discussed. Twenty-eight of 885 (2.8 per cent) injuries involved the C3-C4 vertebrae. Review of these cases reveals that the response to energy inputs at the C3-C4 level differ from that of those involving the upper ...

Computers & concrete, 2009 In the design of concrete columns, it is important to provide some nominal flexural ductility even for structures not subjected to earthquake attack. Currently, the nominal flexural ductility is provided by imposing empirical deemed-to-satisfy rules, which limit the minimum size and maximum spacing of the confining reinforcement.
