Abstract This study is carried out to investigate the effectiveness of using externally applied epoxy mortar on joints of masonry wall panels to enhance their load carrying capacity under axial compressive and lateral loads. A total of six 113 mm thick masonry wall panels of size 1200 x 1200 mm were constructed for this study. Four out of six walls were strengthened using locally available CHEMDUR-31 epoxy mortar on joints. The remaining two walls were tested as control specimens. The control and strengthened wall panels were tested under axial compression and lateral loads. In axial compressi

Abstract:
Cord is a structural element that is generally used to resist relatively large axial loads in tension in comparison to bending and torsional loads. However, in certain cases, a cord may be called upon to resist a compressive load such as occurs when a cord is placed in a composite. When a cord is subjected to compression, the individual filaments lose contact with each other. This results in a considerable reduction in the axial stiffness of the cord. Generally, most cord composites are fabricated at elevated temperatures and cooled to room temperatures. Some remarks are made concerning the bu

The internal pressure of a thin-walled cylindrical structure under axial compression may improve the buckling stability by relieving loads and reducing initial imperfections. In this study, the effect of internal pressure on the buckling knockdown factor is investigated for axially compressed thin-walled composite cylinders with different shell thickness ratios and slenderness ratios. Various shell thickness ratios and slenderness ratios are considered when the buckling knockdown factor is derived for the thin-walled composite cylinders under both axial compression and internal pressure.

In this paper, expressions for the critical axial–torsional loads are derived for the buckling of an elastic rod embedded in an elastic medium. The derivation is based on the assumption that the deforming rod encounters a response force from the surrounding medium, and a first-order perturbation analysis of the governing equilibrium equations. It is shown that a dimensionless universal buckling relationship, independent of material and geometry, exists between the critical axial load, both in compression and tension, and the critical torsional load.

The axial compression strength of concrete columns has been proved to be significantly enhanced by external confinement. In this perspective, the use of Fiber-Reinforced Polymers (FRPs) has been extensively studied. In practical applications, the FRP-confinement is installed on loaded columns, which can already be significantly deformed, while theoretical models neglect this aspect. This paper concerns a new experimental investigation on the possibility that a pre-existing axial load affects the FRP-confinement of concrete.

However, these members are susceptible to various buckling modes including local and distortional buckling and their ultimate strength behaviour is governed by these buckling modes.

Abstract Thin-walled cylindrical shell structure not only shows the highly efficient load carrying capacity but also is vulnerable to buckling instability failure. In practical application, these structures are more easily subjected to locally distributed axial compression load, which is a more common non-uniform loading case. However, until now, the buckling behaviors of thin-walled cylindrical shells under this kind of loading case are still unclear, and there are also few relevant buckling experiments.

Abstract:
Abstract Solder joints in electronic assemblies experience damage due to cyclic thermomechanical loading that eventually leads to fatigue fracture and electrical failure. While solder joints in smaller, die-sized area-array packages largely experience shear fatigue due to thermal expansion mismatch between the component and the substrate, larger area-array packages experience a combination of cyclic shear and axial tensile/compressive loads due to flexure of the substrate. Additionally, on larger processor packages, the attachment of heatsinks further exacerbates the imposed axial loads, as do

Abstract:
The stability problem of a circular cylindrical shell composed of functionally graded materials with Young’s modulus varying continuously in the thickness direction under combined lateral pressure and axial compression loads is studied in this paper. The formulation is based on the first order shear deformation theory. A load interaction parameter is defined to express the combination of applied axial compression and external pressure. The stability equations are derived by the adjacent equilibrium criterion method. These equations are employed to analyze the buckling behavior and obtain the c

Abstract Vertical vessels experience axial compression due to equipment dead weights, vessel contents and environmental loads. ASME BPVC Section VIII Division 2, Paragraph 4.5.17 provides rules for reinforcement of openings in cylindrical and conical vessels subject to axial compression. The rules outlined in the Code only apply to openings not exceeding 25% of the vessel diameter or 80% of the stiffening ring spacing. Openings exceeding these limits are required to be designed by analysis per Section VIII Division 2, Part 5. The rules in Part 4 of Section VIII Division 2 are quite restrictive

Abstract During various daily activities, the gravity as well as external compression loads are transmitted to the pelvis via the lumbar spine. A major portion of this load, accounting for the upper body, is applied on the L1 while the remaining portion is transferred directly through lower lumbar vertebrae L2 to L5. This latter accounts for the gravity and local muscle activities at the lumbar level. The more physiological application of the load distributed at all vertebral levels and not concentrated only at the most proximal one has been demonstrated to markedly stabilize the spine in axia

Abstract The conditions to which flexible pipes are being exposed are becoming increasingly severe. In particular, flexible flowlines that are fully or partially restrained by back fill or rock cover can become exposed to large axial compression forces under pressure and temperature loading. A high True axial compression force may lead to a radial outward displacement of the tensile armour which could eventually exceed the allowable limits of API spec 17J if the axial force exceeds a critical level. Furthermore, when the net Effective axial compressive pipe force exceeds a critical level, the

Abstract:
A previous study on hydrogen cracking in the heat affected zone of pipeline girth welds and repairs found that large strains in the HAZ transverse to the weld played a major role in causing cracking. Large transverse strains were believed to arise from bending of the weld due to the thermal contraction of the weld around the pipe circumference. Large root strains were simulated in the laboratory using a bend test which enabled the effect of material composition and strength to be studied. In the bend test, the specimen deflection at the onset of cracking, indicated by a drop in load, was used

The bending stiffness of joints is a critical factor that impacts the bearing capacity of large-span spatial reticulated shell structures. To address the issue of relatively low bending stiffness of traditional socket joints, a novel type of sprayer joint is introduced in this study. Initially, the bending performance of the socket joint is validated, leading to the proposal of the sprayer joint. Then, a refined finite element model is established to investigate the bending performance of the sprayer joints with varying surrounding bolt radii under axial tension and compression loads.

Abstract:
This study investigates the shear performance of composite cold-formed thin-wall steel walls, particularly in two-story configurations. 9 test groups with varying axial compression and anchor bolt types were examined. Results show that, compared to single-story walls, the two-story walls exhibit lower energy dissipation and ductility, with floor joints being the weak link under cyclic loading. Out-of-plane instability and buckling failure often occur at the floor joint, which is critical to maintaining wall strength. The inter-layer tension bar has little effect on enhancing shear capacity. As

This work proposes a partially through-beam joint system to connect square concrete-filled steel tubular (CFST) columns and reinforced concrete (RC) beams. In the system, the holes in the steel tube allow longitudinal beam reinforcements to be continuous through the joint zone to achieve direct load-transfer of the beam, and the square steel tube with holes is strengthened by welding diagonal ribs located at the corners of the steel tube. Finite element (FE) analyses on joints with RC beams were carried out based on verified models. The analysis results showed that diagonal ribs welded to the
