Seismic upgrading of an RC frame building using double-stage yield buckling-restrained braces

Nowadays, a large number of existing reinforced concrete (RC) structures require strengthening to meet the new building functions and enhanced seismic demands. Double-stage yield buckling-restrained braces (DYBRBs), capable of yielding at different seismic intensities, offer a pr...

Characteristics and Improved Zoning Methods of Wind Load on Ring-Truss Cable Dome Structures under Downbursts

Abstract Downbursts can generate intense winds near the ground, posing a serious threat to large-span structures. This paper explores the wind load behavior of cable dome structures subjected to downburst events. The study employed wind tunnel pressure tests, in which an impingin...

Torsional behavior of reinforced slag-based geopolymer concrete columns under compression

Although extensive research has been conducted on geopolymer concrete (GPC) at material level, its structural behavior under complex stress states remains inadequately understood, especially under combined compression and torsion. In this study, monotonic torsion tests under comb...

Experimental and static performance of a stiffened transfer system in a mountain-shaped frame

Abstract The steel-reinforced concrete stiffened transfer system in the Beijing-Hangzhou Grand Canal Museum features a complex annular vierendeel truss and cantilever wall-columns supporting a 9–15 story mountain-shaped frame. To validate its structural performance, static monoto...

Facilitating megacity electricity decarbonization via grid-interactive demand-side resource management

City power systems face intensified mismatches between generation and dynamic demand under rising zero-carbon energy penetration levels. Although demand-side resource management offers mismatch mitigation potential by regulating load patterns, its city-level capability remains un...

Mechanical Performances of CFRP Rods Under Tension‐Bending Load: Experimental and Theoretical Analysis

ABSTRACT Carbon fiber‐reinforced polymer (CFRP) rods with the advantages of lightweight, high strength, corrosion, and fatigue resistant have a promising application prospect in the field of engineering structures. Due to the lack of mechanical performances and theoretical predic...
