Reinforced masonry

Bulletin of the New Zealand Society for Earthquake Engineering, 1972
It is interesting to recall I. L. Holmes’ comment from the Seminar on Seismic Problems in Structural Engineering 1968 - "reinforced masonry can be designed by the same rules as reinforced concrete". This is really the
theme of this paper. What Holmes said in 1968, on scant evidence, has been shown in the testing which has been conducted since then to ...

Possibilities of using sulphur and plant origin waste for light-weight and thermal insulation construction composites

Journal of Environmental Engineering and Landscape Management, 2013
The article notes that not all types of plant origin waste are appropriate for being used as fuel or left for decay. The environment is polluted by noxious gas that is generated in the process of heating or decaying. Sulphur waste is produced at chemical

Multi‐Scale Bionic Structure Constructs Biomass Flame‐Retardant Thermal Insulation Foam Material

Advanced Science, EarlyView.
Inspired by mussel adhesion and hierarchical brick‐and‐mortar architectures, a cellulose‐based biomimetic foam is constructed by anchoring bentonite nanosheets onto a polydopamine‐decorated cellulose nanofiber network. The resulting foam combines low thermal conductivity with intrinsic flame retardancy and full biodegradability, presenting a ...

Prospecting of Architectural Features Using LiDAR‐UAV Technology, Deep Neural Networks and Visualization Techniques: A Case Study in Kuélap and Cambolín (NW Peru)

Archaeological Prospection, EarlyView.
ABSTRACT High‐resolution and accurate synoptic images of terrestrial topography, even in densely forested areas, have proven valuable for archaeology by enabling the identification and characterization of relief patterns associated with ancient human activities. This study presents a novel approach that integrates digital terrain models (DTMs) obtained

Modelling formation and development of longitudinal cracks in concrete crossing corroding reinforcement

Journal of Civil Engineering and Management, 2002
Tensile stresses in concrete occur under the action of reinforcement rust pressure. When they exceed concrete tensile strength or concrete extension strain exceeds limit value, concrete cracks.
