The behavior of high-strength, fiber-reinforced concrete (HSFRC) beams under concentrated loads was affected by many different aspects, such as the type fibers used and volume percent fibers; nevertheless, primarily modifying shear span-to-depth ratio (a/d). In this experimental investigation, influence a/d ratios (ranging from 1.5 to 2.2) is investigated on response twelve high-strength contai...

The applications of GeoPolymer Concrete (GPC) with basalt-fiber-reinforced-polymer (BFRP) reinforcements could be alternative for conventional structural designs Portland Cement reinforced steel bars green and sustainable constructions. Very limited studies, however, have been carried out to investigate the performance GPC beams BFRP subjected static loads, no study their under impact load is a...

Abstract Even after decades of intensive research, assessing rock slope stability remains a challenge. One reason for this is the spatial variability bridges (RBs) related to non-persistent, pre-existing geological structures, especially as detection RBs generally limited post-failure period. Thus, identification and classification their inclusion in numerical studies are demanding, yet essenti...

This paper proposes a method of flexural analysis for structural performance evaluation the RC secondary flat walls without wall vertical rebar anchorage. An idealized deformation model restrained axial elongation was also proposed and applied to analysis. Consequently, results from had good agreements with experimental results, which identified failure mode in flexure tested specimens. Further...

A nano-displacement sensing method for micro-opto-electro-mechanical-systems (MOEMS) is proposed. The method is based on a square attice photonic crystal (PC) made of dielectric silicon posts, mounted on a micro mechanical flexure. The flexure is fixed at one end and is free to ove at the other, to enable elastic deformations that, by being transferred to the photonic crystal array, modify its ...

of bridges are typically based on simplified analyses or empirical data from recent earthquakes. Since earthquake damage data are very scarce in the central and southeastern United States (CSUS), using analytical methods is the only feasible approach to obtain fragility curves. In 1990, bridges in the CSUS began incorporating seismic details. Some of the changes included the component design fo...

Bulk dissipation of a sandpile on a square lattice with the periodic boundary condition is investigated through a dissipating probability f during each toppling process. We find that the power-law behavior is broken for f>10(-1) and not evident for 10(-1)}>f>10(-2). In the range 10(-2)>or=f>or=10(-5), numerical simulations for the toppling size exponents of all, dissipative, and last waves have...

In the quest to obtain a precise set of aircraft attitude parameters the modeling of wing flexure can become an important issue, especially when short baselines are being used. Previous techniques for the estimation of wing flexure have relied on a constrained Least Squares process to determine the displacement at each epoch before the estimation of the attitude parameters. As will be shown in ...

In this article, we propose a Flexure-FET (flexure sensitive field effect transistor) ultrasensitive biosensor that utilizes the nonlinear electromechanical coupling to overcome the fundamental sensitivity limits of classical electrical or mechanical nanoscale biosensors. The stiffness of the suspended gate of Flexure-FET changes with the capture of the target biomolecules, and the correspondin...

Flexural toppling is typically observed in anti-dip bedding rock slopes with a set of steeply dipping parallel joints against the slope face. This failure occurs due to bending strata, similar cantilever beams. However, exact surface usually unknown, which leads an assumption regarding location and shape that must be made theoretical analysis. serves as basis for stability analysis but may lead...
