The longitudinal variation of soil properties has a major influence for many types structure, including pavements, buried pipes, raft foundations and railways, as it induces stresses and/or displacements that cannot be predicted when assuming homogeneity. A set simple numerical models been developed to describe how soil–structure interaction can influenced by variability. These include: (a) description the spatial variability, within frame geostatistics, where correlation length is main...

CLT-concrete composite floor systems are a solution for timber buildings with long-span floor. It yields reduction of carbon footprint and even eco-friendly structure at the end its service life. This study will evaluate structural performance notched connectors in floor, comprised serviceability stiffness, maximum load, behavior failure. The parameters test plan loaded edge length, notch depth, concrete thickness, screw length. Other secondary variables also assessed, such as different...

This paper presents a review on combining NDT techniques, such as rebound hammer and ultrasonic pulse velocity, for assessing concrete compressive strength. These methods, though being favorably not invasive easy to be extended larger number of elements, are affected by many contingency factors. The SonReb technique suggests the two methods partially offset their low reliability if considered separately. For years, this concept was introduced in order improve evaluation compared with use one...

Abstract The structural capacity of existing buildings is frequently questioned due to various reasons, including age, exposure harsh environments, material degradation, and changes in building codes or use. non‐destructive assessment situ concrete strength, achieved by combining testing (NDT) with destructive coring, offers an interesting approach addressing this concern. Conditional based on information provided previous NDT measurements, significantly improves the accuracy strength...

An objective of infrastructure asset management drinking water network is to minimize risks (service outage or disruption vehicular traffic). However, there are several methods assess their frequency. This paper first discusses the different models used in predicting structural deterioration because it a compulsory preliminary step calculate risk. Risk for service then discussed.

Performance-based earthquake engineering (PBEE) has emerged as a powerful method of analysis and design philosophy in engineering. Structures are generally assumed to be fixed at their bases the process under dynamic loading. Response structures earthquakes is strongly influenced by soil-structure system. In interaction (SSI) problems, ability predict coupled behaviour soil structure essential requires combined models. context PBEE, this paper combines structural seismic response SSI...

The uncertainty in terms of soil characterisation is studied to assess its effect on the structural behaviour extended structures as sheet pile walls. A finite element model used. This integrates a numerical soil–structure interaction together with stochastic that allows characterising variability. serves propagating variability and system parameter uncertainties. Discussion mainly focused two points: (1) testing sensitivity wall different geotechnical parameters (2) assessing influence...

This paper applies the Sobol's variance-based global sensitivity analysis to determine contribution of input parameters structural lateral displacement considering damping and taking into account soil structure interaction (SSI) process. method includes main effect, total effect provides specific parametric for each input. The considered are Poisson's ratio, density, shear wave velocity, damping. N2-SSI simplified procedure is used estimate SSI model RC structure. nonlinear allows assessment...

Inspection-based maintenance strategies can provide an efficient alternative for ageing civil engineering components subjected to and degradation. The technical and/or economic efficiency of such depends on many factors, as the mechanisms involved in loss performance; availability, cost inspection techniques; relation between what be measured through inspections level performance structure; required serviceability direct indirect losses due a reduction structure. On this basis, it is studied...
