So far analytical methods on collapse assessment of three-dimensional (3-D) steel frames have mainly focused on a single-column-removal scenario. However, the collapse of the Federal Building in the US due to car bomb explosion indicated that the loss of multiple columns may occur in the real structures, wherein the structures are more vulnerable t...

FRP plates offer the advantage of lightweight construction, yet their susceptibility to buckling poses a challenge. By incorporating FRP laminates with optimized stiffness, achieved through variable stiffness techniques, this issue can be effectively addressed, enhancing performance under various loading conditions while adhering to specified const...

This paper investigates, experimentally and numerically, the buckling behavior of innovative sustainable Low-Cost Bamboo Composite (LCBC) structural columns under compressive loading. The LCBC columns are manufactured from bamboo culms in combination with bio-based resins to form composite structural columns. Different LCBC cross-sectional configur...

Rail dampers typically provide 3–4 dB(A) noise reduction, but occasionally 5–10 dB(A) for lightly damped rails on soft fasteners (Ho et al. in Noise and vibration mitigation for rail transportation systems. Springer, pp 89–96, 2012; Thompson et al. in Appl Acoust 68:43–57, 2007; Lo et al. in Noise and vibration mitigation for rail transportation sy...

Rail damper is a retrofit solution for excessive noise and vibration from the rail. Rigid Contact Tuned Mass Rail Damper (RCTMD), a new type of rail damper, can be tuned to rail resonance frequency for specific site requirements to address noise issues stemming from rail courrgation, rail pin-pin resonance (vertical and lateral directions) and P2 r...

The combined mass of wheelset and rail exhibits a simple harmonic motion on the resilient fastener. The natural resonance mode of this motion is called P2 resonance. P2 resonance typically happens at a frequency around 30–100 Hz proportional to the square root of the stiffness of the resilient fastener. Railway Groundborne noise (GBN) at the buildi...

Layer separation (delamination) is an essential threat to fiber-reinforced polymer (FRP) plates under dynamic, static, and fatigue loads. Under compressive load, the growth of delamination will lead to structural instability. The aim of this paper is to present a method using shape memory alloy (SMA) stitches to suppress the delamination growth in...

Dynamic buckling of structure is one of the failure modes that needs to be considered since it may result in catastrophic failure of the structure in a short period of time. For a thin fiber-reinforced polymer (FRP) plate under compression, buckling is an inherent hazard which will be intensified by the existence of defects like holes, cracks, and...

Tuned mass rail dampers are cost effective for the mitigation of the airborne noise and vibration with the ability to be tuned for individual site. TMDs have been developed and installed at a single rail in a curve tunnel and achieve more than 4dB(A) noise reduction in many cases. According to the on-site noise reduction performance during damper i...

• P2 resonance is a simple harmonic motion of rail and wheelset in-phase bouncing together on elastic support (Resilient baseplate of ~8 to 50kN/mm, rail pad of ~50 to 300kN/mm) • ~35 to 50Hz P2 resonance for support stiffness of 15 to25kN/mm and wheelset weight of 1000 to 1600kg, • When P2 frequency close to sleeper passing frequency (30 to 50Hz...

• Short-pitch (25-50mm) rail corrugation often appears in Low Rail (LR) in curve track on resilient baseplates • Low rail corrugation appears to be related to lateral pin-pin resonance in almost all our observed cases (independent of training speed and tracking curvature) • Corrugation (~30mm) induced vibration frequency at ~570Hz (300m radius c...

In recent years, researchers have focused on retrofitting methods to strengthen deteriorating buildings and enhance the bending capacity of structural elements.

The spatial and time variations of the martensite volume fraction due to the localized and time variations of the stress distribution along shape memory alloy wires embedded in composite plates have not been considered in the majority of the available researches. In the present research, an accurate algorithm is proposed to determine the localized...

Embedding Shape memory alloy (SMA) wires in laminated cylindrical shells can improve the instability of the structure. The superelasticity and high damping capacity of them would result in enhancement of buckling loads of panels under constant temperature. Many studies on thermo-mechanical analysis of hybrid composite plates with embedded SMA wires...
