“…Previous work by the authors has shown that the behavior of tall frames to component removal is almost always governed by loss-of-stability failures which can lead to the complete collapse of a building Gerasimidis et al, 2016). However as shown in previous work , the capacity of a tall building to an external blast event is higher when the lateral resisting system of the building is located at the perimeter of the structure.…”

The ingenuity of structural engineers in the field of tall and super-tall buildings has led to some of the most remarkable inventions. During this evolution of structural engineering concepts in the last 100 years, the technical challenges that engineers encountered were extraordinary and the advances were unprecedented. However, as the accomplishments of structural engineers are progressing, the desire for taller and safer structures is also increasing. The diagrid structural system is part of this evolving process as it develops a new paradigm for tall building design combining engineering efficiency and new architectural expression. The first appearances of this type of tall buildings have already been constructed and the interest of both engineering and architectural communities is growing mainly due to the many advantages compared to other structural systems. This paper presents a simple approach on optimizing member sizes for the diagonals of steel diagrid tall buildings. The optimizing method is based on minimizing the volume of the diagonal elements of a diagrid structure. The constraints are coming from the stiffness-based design, limiting the tip deflection of the building to widely accepted regulative limits. In addition, the current paper attempts to open the discussion on the important topic of optimization and robustness for tall buildings and also studies the future of the diagrid structural system.

“…However, in practical engineering, nonlinear and dynamic factors will simultaneously produce effects on structure, which may lead to large computational error. Thus, progressive collapse specifications need to be further perfected and supplemented [32,33].…”

A finite element model (FEM) of frame-shear structure was constructed using OpenSees program based on the nonlinear flexibility theory and multi-vertical-line theory that considered bending-shear coupling, and its progressive collapse resistance under abnormal conditions was analyzed. Flexibility-based method for modeling shear wall finite element and multi-verticalline element (SFI-MVLEM) was proposed. Method of deleting failure component elements was presented, as well as the model solving algorithm. The FEM was validated by the completed structure test. On these bases, 3 groups of typical frame-shear structure systems were designed to perform nonlinear dynamic collapse analysis under different initial failure conditions, in order to study the impact of the number of floors and earthquake resistant design on the progressive collapse resistance of frame-shear structures. Analysis results showed that, at initial failure of frame column, the residual shear wall element can well complete the internal force redistribution of structure to provide alternative force transmission path, thereby forming antiprogressive collapse force. In the case of initial failure of shear wall, C-shaped shear wall can form alternative path to diminish the vertical deformation of frame-shear structures. Final comparison shows that the structural seismic design can effectively improve their anticollapse performance.

“…The response of the research community to the phenomenon has focused around three main themes: computational (Main et al 2014, Kwasniewski 2010, Li et al 2014, Bao et al 2016, Pantidis and Gerasimidis 2017b, Pantidis et al 2018b), experimental (Johnson et al 2016, Dinu et al 2016, Gouverneur et al 2013, Weigand and Berman 2013 and theoretical (Izzudin et al 2008, Pantidis and Gerasimidis 2016, Pantidis and Gerasimidis 2017a, Pantidis and Gerasimidis 2018a,, Gerasimidis 2014. Theoretical approaches to the investigation of the progressive collapse phenomenon have been appearing in the literature with a lower frequency due to the inherent complexity of the problem at hand and the difficulty to describe the nonlinear phenomena associated with it.…”

The prevailing analysis approach in the field of disproportionate collapse of structures is the alternate path method (APM). This method adopts the notion of a complete removal of a key load-bearing component of the system, such as a column or a shear wall, and investigates the capability of the remaining structure to bridge over the loss of this component. Though it offers a practical and efficient tool for the assessment of structural robustness, the complete column loss scenario is a rather unrealistic idealization of damage initiation. This study expands on previous work done by the authors in the field of structural robustness and applies a partial distributed damage method (PDDM) in 3D multi-story steel framed and concrete composite buildings. This method assumes that damage is being distributed in more than one components, as a common output of real-case extreme events. Using advanced nonlinear finite element modeling, this work applies a PDDM scenario in a prototype structural system and evaluates its mechanical performance, making direct comparisons with the APM with regards to the governing collapse mechanism, structural capacity, and damage progression path.Structures Congress 2020 Downloaded from ascelibrary.org by 44.224.250.200 on 07/16/20.
