In recent years, high-rise connected structure is a structure form that is used widely, in order to research the structure's dynamic characteristics, and improving the structure's seismic performance. This paper adopts large finite element software ANSYS to establish finite element model of high-rise connected structure, uses dynamic time history analysis method for seismic response calculation, and analyses and explain calculation results. Through the analysis, under the action of Tianjin wave, the maximum horizontal displacement value of high-rise connected structure's 23rd floor is 0.07765m, it appears in 2.26s; under the action of Tianjin wave, the maximum horizontal acceleration value of high-rise connected structure's 23rd floor is 1.90251m/s 2 , it appears in 1.64s. Research results show that seismic behavior of high-rise connected structure is good, can satisfy the engineering requirement and as well as can provides a certain theoretical basis for seismic design of high-rise connected structure.

“…In this study, for the sake of simplicity and reducing the computational time, the analyses are performed on the planner response of a 2D model. It is yet evident that 3D models can provide detailed information on the response of structures as well discussed in studies performed by Fu and Pyl et al When a 2D model is considered, additional robustness provided by the concrete slab is not taken into account. Nevertheless, the effect of the concrete slab is further highlighted over the cooling phase where different rate of losing–gaining temperature is observed in different parts of the floors.…”

Summary This paper investigates the structural fire response of steel beam‐supporting column transfer structures. Two three‐story (Case 1) and seven‐story (Case 2) structures with different span lengths are designed first to withstand gravity and seismic loads. All the structural members are also designed to meet their required fire resistance ratings based on the ISO834 fire. The structural vulnerability is then evaluated under two fire scenarios: the natural fire as a uniform and the traveling fire as a nonuniform temperature distribution inside the structures. The fire loads are applied to the first story of the structures where the structural irregularity is evident. The natural fires are determined based on Eurocode 1 and based on different opening ratios of 0.04, 0.067, 0.08, 0.12, and 0.16 to provide different duration of the heating phase. The results indicate that under the uniform fire scenarios, Case 1 collapses after 134 min under the opening ratio of 0.04. As well, Case 2 collapses under the opening ratios of 0.04, 0.67, and 0.08 at 95, 142, and 160 min, respectively. The results also show that under the nonuniform fire with a size of 25%; Case 1 collapses at 89 min, and Case 2 collapses at 93 min. Although it is believed that the cases studied should logically remain stable under possible fire scenario, the results indicate that this is not a true presumption. The results of this study provide beneficial information about structural fire response of beam‐supporting column transfer structures as an important structural irregularity.

“…Their possibilities are, for obvious economic reasons, heavily investigated by working groups of EC3, to which the Belgian researchers have always offered significant contributions, amongst others (Pyl et al [13][14][15][16]). The Laboratory of Steel Constructions in the University of Liège, founded by Charles Massonnet, are worldwide known especially in the field of joints, and the actual group, headed by J.P. Jaspart, is regularly strengthened by its collaboration with L. Pyl, who contributed to their scientific activities.…”

Two departments of Vrije Universiteit Brussels (VUB), being the Department of Architectural Engineering (ARCH) and the Department of Mechanics of Materials and Constructions (MeMC), both in the Faculty of Engineering, are both scientifically active in various aspects of structural and architectural engineering. What, at first sight, could be seen as reciprocal attempts to cover each other's fields of research activities is far from the truth. On the contrary, their continuous collaboration, which originated years ago, showed an intense synergy, not only in the field of scientific research, but also in teaching and external activities. The present paper illustrates that statement with case studies, taken in the three activity components, from the point of view of the structural engineer and shows that "one and one can be (significantly) more than two".A parallel paper will report on the point of view of the architectural engineer at VUB.
