Reliability-based safety map for Howe-type trusses under uncertain Nigerian wind loading

Journal of Infrastructure Preservation and Resilience
The current practice in civil engineering is to provide designs with a certain level of safety, which makes it necessary to forecast how a system will perform with minimal or no prior knowledge.

Influence of Staggered Truss on Progressive Collapse-Resistant Behavior of Steel Frame Structures

Buildings
In order to study the effect of the support mode of a staggered truss system on the continuous collapse resistance performance of a steel structure, four finite element models were established based on the bracing arrangement of a five-story steel frame ...

Experimental Study and Finite Element Analysis on the Bearing Capacity of a Novel Light-Steel Truss with Cap-Shaped Chords

Buildings
Aiming to address the shortcomings of traditional large-span light-steel trusses, such as low bearing capacity and inconvenient on-site assembly, this paper proposes a novel cap-shaped chord light-steel truss.

Temperature Field and Gradient Effects for Concrete-Filled Steel Tubular Truss Arch Bridges Under Construction

Buildings
Long-span concrete-filled steel tubular truss arch bridges are extremely sensitive to thermal effects during cantilever construction, with non-uniform temperature distributions arising from mutual shading between members.
