Seismic response of reinforced concrete frame structures with infill walls [PDF]

, 2008
Reinforced concrete (RC) frame structures with infill walls, usually of unknown strength, are commonly used in developing countries. Current seismic codes used in these countries lack adequate consideration of the infill material and give wide options to

Orthodentine‐osteodentine and osteocytic‐anosteocytic transition inferred from Silurian stem chondrichthyan dermal jawbones with ever‐white teeth overgrown by brown denticles

Developmental Dynamics, EarlyView.
Abstract Background The dentigerous jawbones of a 423‐million‐year‐old stem chondrichthyan (ischnacanthid acanthodian) carry a characteristic combination of multi‐row non‐shedding white teeth with brownish overgrowing denticles. The color distinction makes it a good model for observing the interaction between two odontode lineages, but the nature of ...

Design Internal Forces of Non‐Dissipative Members in CBFs With Regular and Irregular Brace Configurations

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Steel Concentrically Braced Frames (CBFs) are widely used in seismic regions, with chevron and split‐X configurations commonly adopted for their structural efficiency and architectural flexibility. Although extensive research has been carried out on these systems, the effectiveness of the formulations available in the literature for estimating

The effect of masonry infill walls on the reinforced concrete frames behavior under lateral load

Journal of Materials and Engineering Structures, 2020
The reinforced concrete structures with masonry infill walls are widely used to construct buildings in Algeria, as in many parts of the world. According to earthquake analysis, this type of construction can undergo serious damage under seismic load.

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 ...

Stiffness optimized structures with variable density gyroid lattice infill for extrusion additive manufacturing

Additive Manufacturing Letters
Additive manufacturing has enabled the fabrication of sparse lattice structures with complex geometries tailored to specific uses. These lattice infills provide attractive properties while weighing less than a fully solid part and satisfying the strength

Controlled seismic behaviour of masonry-infilled steel frames

Građevinar, 2016
Whether used as a curtain/partition wall or a bearing part of the structure, masonry infill significantly affects structural behaviour of the primary structure.
