Average stress-average strain tension-stiffening relationships based on provisions of design codes

引用

Journal of Zhejiang University-science A(Applied Physics & Engineering) 2011年第10期12卷 731-736页

作者： Gintaris KAKLAUsKAs viktor GRIBNIAK Rokas GIRDZIUs Department of Bridges and special structures Vilnius Gediminas Technical University Department of strength of Materials Vilnius Gediminas Technical University

This research was aimed at deriving average stress-average strain tension-stiffening relationships in accordance with the provisions of design codes for reinforced concrete （RC） members. Using a proposed inverse technique, the tension-stiffening relationships were derived from moment-curvature diagrams of RC beams calculated by different code methods, namely Eurocode 2, AC1318, and the Chinese standard GB 50010-2002. The derived tension-stiffening laws were applied in a numerical study using the nonlinear finite element software ATENA. The curvatures calculated by ATENA and the code methods were in good agreement.

A new global ocean hydrographic climatology

引用

Atmospheric and Oceanic science Letters 2019年第3期12卷 226-229页

作者： GOURETsKI viktor Center for Earth system Research and sustainability University of Hamburg International Center for Climate and Environment sciences Institute of Atmospheric Physics Chinese Academy of Sciences

This report describes the main features of the recently published World Ocean Experiment–Argo Global Hydrographic Climatology. This climatology is based on profile data from ships, Argo floats, and sensors attached to marine mammals. As an important deviation from the widely used climatologies produced previously by the National Oceanographic Data Center, the spatial interpolation was performed on local potential density surfaces, so that no ‘artificial water masses’ were created. In addition to monthly fields of temperature and salinity, gridded maps of the upper mixed layer depth are now provided.
