To investigate the seismic response characteristics of piled wharf structures, a numerical model soil-structure interaction system is established. Extensive fiducial error and grey correlation analyses are also conducted to obtain degree sequence internal force structure deformation, as well acceleration surrounding soils. The results show that peak at typical point soil more sensitive variatio...

Vibration-based structural damage detection (SDD) has been a subject of intense research in health monitoring (SHM) for large civil engineering structures over the decades. The performance conventional SDD approaches predominantly relies on rational choices feature and classifier. Hand-crafted features or fixed classifiers would not be optimal choice all damaged scenarios. This paper proposes n...

Due to the harsh working conditions, durability of seaport wharf structure is poor compared with similar hydraulic structures. According structural characteristics coastal port and particularity a high salt humidity environment, stress features are analyzed, health inspection indicators proposed. A fiber grating sensor-based monitoring system for high-pile piers established. corresponding detec...

Integral bridges are a class of with integral or semi-integral abutments, designed without expansion joints in the bridge deck superstructure. The significance an design is that it avoids durability and recurring maintenance issues joints, maybe bearings, which prevalent traditional bridges. less costly to construct. They require therefore cause traffic disruptions incur socio-economic costs. A...

In “Bulgarian Solitaire”, a player divides a deck of n cards into piles. Each move consists of taking a card from each pile to form a single new pile. One is concerned only with how many piles there are of each size. Starting from any division into piles, one always reaches some cycle of partitions of n. Brandt proved that for n = 1+2+ · · ·+k, the cycle is just the single partition into piles ...

in this paper, evaluation of torsional stiffness in beam and slab bridge deck elements is presented. a beam and slab bridge decks structurally behave as a grillage. a grillage has an efficient transverse load distribution due to transverse asymmetric load. in the case of bridge deck without transverse beams in the span, transverse load distribution depends on the torsional stiffness of longitud...

a simplified approach for nonlinear analysis of the load-displacement response of a single pile and a pile group is presented using the load-transfer approach. a hyperbolic model is used to capture the relationship between unit skin friction and pile-soil relative displacement developed at the pile-soil interface and the load-displacement relationship developed at the pile end. as to the nonlin...
