A mason-inspired pattern generator for historic masonry structures using quality indexes
Engineering structuresA considerable amount of historic masonry structures (HMS) are composed of irregular stone. However, few studies have systematically investigated the influence of masonry patterns (or masonry unit arrangements) on structural behaviour.

Masonry structures in the presence of foundation settlements and unilateral contact problems
, 2020 This paper aims at presenting a new perspective on the modeling of the influence of foundation settlements in masonry structures. We show that it is possible to model in a consistent way the crack pattern and the associated mechanism induced by applied ...

Three-dimensional discrete element modelling of rubble masonry structures from dense point clouds
Automation in Construction, 2020 This paper presents a framework for the three-dimensional structural analysis of full scale, geometrically complex rubble masonry structures from point clouds generated from Structure-from-Motion photogrammetry or terrestrial laser scanning. According to

Modeling Approaches for Masonry Structures [PDF]
The Open Civil Engineering Journal, 2014 Different scale approaches, micromechanical, multiscale and macromechanical or phenomenological, are presented to study the structural response of masonry elements. First, a micromechanical model is introduced and the masonry is considered to be a heterogeneous material, made of mortar and bricks joined by interfaces, where the mortarbrick decohesion ...

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 ...

Journal of Civil Engineering and Management, 2001 Joint action at the interface of concrete and profiled steel sheet layers of composite structures can be achieved in various ways. In most cases different types of roughness (embossments) are made inside sheet waves, which increase mechanical bond ...

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

Strengthening and Rehabilitation of U-Shaped RC Bridges Using Substitute Cable Ducts
Advances in Materials Science and Engineering, 2019 The presented paper deals with strengthening and rehabilitation of U-shaped reinforced concrete bridges from the period of 1905–1930 using post-tensioning, which is a suitable, reliable, and durable method.
