Analysis of flood impacts on masonry structures and mitigation measures

Journal of Flood Risk Management, 2021
The impact of floods can be devastating to buildings, especially in countries and villages in mountainous areas. Based on the flood impact risk analysis results, two methods are suggested by authors to improve the flood impact defense capability of rural

Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

Deep Underground Science and Engineering, EarlyView.
Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

Effect of Thin Cement-Based Renders on the Structural Response of Masonry Wall Panels

Applied Sciences, 2018
URM (Unreinforced Masonry) historic buildings can be generally arranged into three categories: adobe, brick and stone masonry. However, a common feature of URM structures is typically the low mechanical properties of the masonry material, especially in ...

Numerical and Experimental Evaluation of a Simplified Lateral Spring Formulation for Rocking Structures

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Rocking podium isolation systems have gained significant research interest as a method of limiting seismic demands on superstructures and eliminating residual post‐earthquake drifts through self‐centring behaviour. However, while numerous models of varying complexity, including analytical, phenomenological, and physical formulations, have been

Evaluation of an Approximate Seismic Assessment Procedure for Load-Bearing Masonry Buildings

Infrastructures
The Building Inspection Priority Index (BIPI) method for masonry structures is an approximate procedure for the preliminary assessment of the seismic capacity of existing load-bearing masonry buildings and for the prioritization of each building for ...

Structural conditioning factors of the installation of rooftop hvac equipment on existing load-bearing masonry buildings: case study

Revista Ingeniería de Construcción, 2021
The growing interest in providing adequate Heating, Ventilation and Air Conditioning (HVAC) conditions for those public buildings in which they were not originally planned frequently leads to the need to install HVAC units of significant dimensions and ...

Seismic Response of Existing Masonry‐Infilled RC Frame Structures Retrofitted with Steel Exoskeletons

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Considering the needs for reducing carbon emissions and except for extreme cases of very degraded existing structures, research on technologies allowing continued use or upgrading of older buildings has become a priority topic. Generally, research on upgrading of reinforced concrete frame structures certainly has a prominent role, because of ...

Influence of the Boundary Conditions on the Seismic Response of Existing Masonry Infills From In‐Plane and Dynamic Out‐of‐Plane Tests

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Despite increasing attention to the seismic performance of masonry infills, their out‐of‐plane dynamic behaviour remains insufficiently explored, particularly under pre‐existing in‐plane damage. This study presents a comprehensive experimental campaign designed to investigate the seismic behaviour of an existing weak masonry infill typology ...

Constructional Features of the Stiffness of Shearwalls in Lightweight Steel Framed Buildings

Slovak Journal of Civil Engineering, 2019
For low-rise buildings frame technologies using lightweight thin-wall steel constructions have become significantly widespread. The main influence on a building’s spatial rigidity under lateral forces is taken by shearwalls.
