Optimize Q690 beam-column connections for seismic resilience and replaceability

High-strength Q690 tubular joints are widely adopted in coastal and marine steel structures, while corrosion damage severely deteriorates their mechanical properties and load-carrying safety. Degradation Behavior and Bearing Capacity of Corroded Q690 Tubular Joints conducts in-depth research on the degradation behavior and residual bearing capacity of corroded Q690 tubular joints. It elaborates on corrosion damage characteristics of chord walls and weldment, analyzes the interaction between corrosion defects and structural failure modes, and develops prediction methods for residual bearing capacity under corrosive environments.

Integrating laboratory corrosion tests and mechanical loading experiments, this book offers reliable calculation theories and engineering suggestions for durability design, safety evaluation, and maintenance of Q690 steel tubular structures. Degradation Behavior and Bearing Capacity of Corroded Q690 Tubular Joints is a valuable reference for civil and offshore engineering researchers, designers and postgraduates.
