Proposal of concept for structural modelling of hybrid beams

Studia Geotechnica et Mechanica, 2022
Investigation on the behaviour of a hybrid beam is presented. Hybrid beam stands for an element with hybrid cross sections. This means sections that consist of steel and concrete parts, connected together with composite dowels, and both are considered ...

Combining nuclear magnetic resonance and rate-controlled porosimetry to probe the pore-throat structure of tight sandstones

Petroleum Exploration and Development, 2016
Rate-controlled porosimetry (RCP), nuclear magnetic resonance (NMR) and micro CT tests were conducted on five tight sandstone samples, the results were compared to reveal the limitations of RCP in determining the pore size distribution (PSD) and pore to ...

Vapor intrusion in soils with multimodal pore-size distribution

E3S Web of Conferences, 2016
The Johnson and Ettinger [1] model and its extensions are at this time the most widely used algorithms for estimating subsurface vapor intrusion into buildings (API [2]). The functions which describe capillary pressure curves are utilized in quantitative
