Earthquake-induced collapse of steel latticed shell: Energy criterion implementation and experimental validation

Experimental Study on Small-Scale Shake Table Testing of Cable-Stiffened Single-Layer Spherical Latticed Shell

“…Utilizing the energy principle, Xu and Sun [9] identified the precise moment at which a single-layer latticed shell structure becomes unstable under seismic influences by comparing the structural internal energy against the energy input from the exterior, thus accurately estimating the critical peak ground acceleration for the structure. Similarly, Zhu et al [10] derived a method based on the energy principle for assessing the dynamic instability or collapse of latticed shell structures, with the accuracy of the method confirmed through vibration table experiments. In exploring the effects of varying component characteristics on latticed shell structures, Xiong et al [11][12][13] focused their research on single-layer latticed shell structures incorporating semi-rigid aluminum alloy nodes.…”

Evolution characteristics and performance evaluation of extended end-plate joints with single and double side connections under cyclic loading

“…Accurately assessing the instability characteristics of plate connection joints under complex loads such as earthquakes and wind loads is crucial for the safety and reliability of structures. The risk of failure at critical locations [ 5 , 6 ] in plate connections can lead to catastrophic collapses of buildings [ 7 , 8 ]. This risk can be attributed to the sequential evolution of performance [ 9 ] and the cumulative progression of damage, representing the gradual transformation of the energy system in plate joints from quantitative to qualitative changes, continually triggering failure risks [ 10 ].…”
