Life cycle assessment (LCA) of concrete made using recycled concrete or natural aggregates
(Elsevier Inc., 2013)
This chapter is devoted to comparative environmental assessment of structural concrete made with recycled concrete aggregates and structural concrete made with natural aggregates. The results of life cycle assessment of ...
Concave Regular Faced Cupolae of Second Sort
(Dresden: Technische Universität Dresden; International Society for Geometry and Graphics (ISGG), 2008)
Cupola is a polyhedron which is consisted of two regular polygons: n-gon and 2n-gon in parallel planes, connected by alternating sequence of squares and equilateral triangles, i.e. Johnson’s solids J3, J4 and J5. However, ...
Effect of bed elevation discordance in the main river on the confluence hydrodynamics in 90 degrees straight-channels' confluences
(CRC Press/Balkema, 2014)
A role of the difference in bed elevations in the main-river (Delta z(MR)) at its entrance to a 90 degrees straight-channels' confluence is studied numerically using a 3D finite-volume model. Three characteristic hydrological ...
Numerical modelling of glulam beams externally reinforced with CFRP plates
(Vienna University of Technology, 2016)
Timber beams can effectively be reinforced using externally bonded fibre reinforced polymer (FRP) composites. This paper describes a nonlinear 3-dimensional finite element model which was developed in order to accurately ...
Flexural behavior of reinforced recycled aggregate concrete beams under short-term loading
(Materials and Structures, 2013)
Recycling of waste concrete is one of the sustainable solutions for the growing waste disposal crisis and depletion of natural aggregate sources. As a result, recycled concrete aggregate (RCA) is produced, and so far it ...
Modeling Indoor Particulate Matter and Small Ion Concentration Relationship-A Comparison of a Balance Equation Approach and Data Driven Approach
(MDPI, 2020)
In this work we explore the relationship between particulate matter (PM) and small ion (SI) concentration in a typical indoor elementary school environment. A range of important air quality parameters (radon, PM, SI, ...
Efficient discretization of circular cross-section in fiber beam/column element
(The 16th International Conference on Civil, Structural & Environmental Engineering Computing, Riva del Garda, Italy, 2019)
