Simplified static vertical loading test on sheet piles using press-in piling machine

Green's function probe of a static granular piling.

We present an experiment which aims to investigate the mechanical properties of a static granular assembly. The piling is a horizontal 3D granular layer confined in a box. We apply a localized extra force at the surface and the spatial distribution of stresses at the bottom is obtained (the mechanical Green's function). For different types of granular media, we observe a linear pressure respons...

Simplified Statement Extraction Using Machine Learning Techniques

The automatic generation of basic, factual questions from a single sentence of text is a problem in the field of natural language processing (NLP) that has received a considerable amount of attention in the past five years. Some studies have suggested splitting this problem into two parts: first, decomposing the source sentence into a set of smaller, simple sentences, and then transforming each...

Assessment of the Condition of a Beam Using a Static Loading Test

This paper presents a novel approach for structural damage detection. The cross-entropy method is used to estimate the structural parameters of a simply supported beam from its response to a static load consisting of a heavy vehicle. Various states of beam damage are modelled through local reductions in flexural rigidity. The proposed method estimates the distribution of stiffness throughout th...

Study on Finite Element Model Updating in Highway Bridge Static Loading Test Using Spatially-Distributed Optical Fiber Sensors

A finite model updating method that combines dynamic-static long-gauge strain responses is proposed for highway bridge static loading tests. For this method, the objective function consisting of static long-gauge stains and the first order modal macro-strain parameter (frequency) is established, wherein the local bending stiffness, density and boundary conditions of the structures are selected ...
