We present the results of a large-scale experimental campaign performed on prototype structure EuroProteas in Thessaloniki, Greece, to assess effectiveness gravel-rubber mixture (GRM) layers underneath shallow foundations as means geotechnical seismic isolation (GSI). found that GSI structures is optimized by increasing rubber content soil-rubber up 30% per weight. The systems has been investig...

The subgrade soil stiffness, which depends on the in-situ moisture content and index characteristics, is a key factor in pavement rutting. Due to variations compaction process used during construction seasonal changes, may deviate from desired condition. resilient modulus (MR), an important parameter of Mechanistic-Empirical (M-E) design process, specify stiffness. Repeated load triaxial tests,...

the nonlocal nonlinear buckling of a double layer graphene sheet (dlgs) covered by zinc oxide (zno) piezoelectric layers is investigated in this study. the surrounding circumstances of the system are considered as a pasternak foundation including spring constants and a shear layer. graphene sheets are subjected to longitudinal magnetic field and biaxial forces. on the other hand, the zno piezoe...

A GREAT DEAL OF UNCERTAINTY exists regarding the effectiveness of safety incentive programs in construction. Most research on incentives involves case studies and theoretical analyses of their advantages and disadvantages. Using primary survey data from construction firms and craftworkers, this article examines the impact of incentives on the safety performance of U.S. construction firms. The s...

Four precast column-to-foundation connection specimens, previously tested under lateral reversed cyclic loading and constant axial load (first-stage tests), were repaired with Carbon Fibre Reinforced Polymer (CFRP) layers in the areas where plastic hinges had formed retested same loads (second-stage tests). The columns originally manufactured ultrahigh-performance concrete (UHPC) high stee-fibr...

Scour erosion poses a significant risk to bridge safety worldwide and affects the stiffness of soil-foundation system, resulting in global changes dynamic behavior bridges. In this paper, new approach detect scour at multiple locations is proposed, using wavelet-based Operating Deflection Shape (ODS) amplitudes. A numerical model with four simply supported spans resting on piers used test appro...

Suction caisson foundations provide options for new foundation systems offshore structures, particularly wind turbine applications. During the design process, it is necessary to make reliable predictions of stiffness foundation, since this has an important influence on dynamic performance overall support structure. The characteristics structure, in turn, its fatigue life. This paper describes a...

The use of the segmental pipe section immersed tunnel suffers from several problems, such as complex construction, weak foundation, great water depth, thickness siltation back on top tube, and difficult settlement control. Based Winkel’s elastic foundation beam theory, a mechanical calculation model is established according to case an inhomogeneous soil layer, force deformation structural syste...

post failure analysis of massive structure infers that soil-structure interaction (ssi) is a crucial phenomena influencing seismic response of massive structures. cable-stayed bridge’s popularity and numbers are increasing now-a-days because of economical longer span & aesthetic good look. the current paper examines the effect of depth of foundation on seismic response of cable-stayed bridg...
