In this paper, a single internal column removal test was conducted for a 1/3 scale 4-bay steel frame with concrete-filled steel tubular (CFST) columns. The anti-collapse mechanism of the frame under the scenario of column loss is discussed. Both FE model and simplified analytical model are...
As explained, the networks were initially derived from the information of 154 CCFSTCs in the training phase. This data was used to assess the efficiency of the models in dealing with unseen column conditions. In this process, when metaheuristic algorithms provide a calculation pattern for the ANNs...
Keywords:high speed collision dynamics; SRC column;CFST column; vehicle impact; dynamic response 近年来,车辆与建(构)筑物的碰撞事故频繁发生,造成了相当大的财产损失和人员伤亡,因此,有必要对车辆撞击结构物的动力响应进行深入研究。在现实生活中,建筑物底层立柱、桥梁立柱、护栏、交通信号结构和电杆是最容易受到...
Besides, a comprehensive finite-element model predicts compact CFST column performance, investigating axial force-moment (P-M) interaction behavior with respect to the material strength ratio (fy/fc′). In the second phase of the study, an ANN model, incorporating input parameters, estimates axial...

Analyzing the feature importance results, it becomes evident that the diameter of the CFST column (D) significantly governs the axial compressive capacity of CFST, indicating notably higher importance compared to other input features. Following closely are the length of the column (L) and the ...
