“…The collapse margin ratio (CMR) was adopted to quantify the resistance capacity of structural collapse. CMR can be calculated as follows using the PGA given in equation (6) because it is popularly used as the ground motion intensity measure (IM) (Lu and Guan, 2017; Tian et al, 2016):…”

“…An incremental dynamic analysis (IDA) was performed to determine the collapse resistance capacity (FEMA P695, 2009; Shi et al, 2014). In accordance with the work in the nonlinear time-history analyses, the 22 records of far-ﬁeld ground motions recommended in FEMA P695 (2009) were adopted in the following analysis, which were widely used for seismic collapse simulations (Lu and Guan, 2017; Lu et al, 2015; Tian et al, 2016).…”

In this study, comparative investigations of a typical steel moment frame and a steel frame-braced core-tube structure, designed following different seismic codes, are conducted to evaluate the significant differences between the Chinese and the United States (US) seismic codes for steel buildings. The study outcomes can enhance the understanding of the differences in steel structure design between two countries, especially the differences in seismic performance. Specifically, the design outputs of the structural components, material consumptions, dynamic characteristics, and seismic loads were analyzed. Subsequently, finite element (FE) models based on the design outputs were established to assess the seismic performance and collapse margin. Furthermore, the local buckling effect of the steel components can be considered in the FE model, which can effectively predict the buckling-induced strength deterioration under excessive deformation. The comparison results reveal that, under the same design conditions in this study, both the strength requirement and deflection limit are critical factors that control the typical buildings design following the Chinese codes. However, the strength requirement is the primary factor that controls the design outcomes following the US codes. Moreover, the collapse resistance of the steel moment frames from both codes are similar, but the material consumption based on the Chinese design code is comparatively higher. In contrast, the material consumption of the steel frame-braced core-tube structures are comparable, but the collapse resistance of the US design code is better. Furthermore, the collapse analyses indicate that the local buckling effect could significantly reduce the collapse resistance.

In this paper probabilistic seismic loss assessment of RC high rise-buildings for seismic excitation typical for Southern Euro-Mediterranean zone is presented. The loss assessment methodology developed in paper is based on a comprehensive simulation approach which takes into account ground motion (GM) uncertainty, the random effects in seismic demand as well as in predicting the damage states (DSs). The methodology is implemented on three RC high-rise buildings of 20-story, 30-story and 40-story with core wall structural system designed according to Eurocode 8. The loss functions described by a cumulative lognormal probability distribution are obtained for two intensity level for a large set of simulations (non-linear time-history analyses) based on 60 GM records with wide range of magnitudes, distance to source and different site soil conditions. The losses expressed in percent of building replacement cost for RC high-rise buildings are obtained. In the estimation of losses, both structural (S) and non-structural (NS) damage for four DSs are considered. The effect of different GM characteristics (magnitude, distance to source and site soil condition) on the obtained losses are investigated. It is checked if the estimated performance of the RC high-rise buildings fulfill limit state requirements according to Eurocode 8.

“…In the field of resilience evaluation of individual buildings, the method of Resilience‐based Earthquake Design Initiative (REDi) (Almufti & Willford, ) can predict the repair time and labor demand of each building according to the widely accepted methods in construction scheduling. This method is extensively used for the seismic resilience assessment of individual buildings (Dong & Frangopol, ; Hutt, Almufti, Willford, & Deierlein, ; Lu, Xie, Yu, & Lu, ; Tian, Lu, Lu, Li, & Guan, ). In the REDi method, the repair sequences of individual buildings and the labor demand of each repair sequence are explicitly presented.…”

A city‐scale time–history analysis‐driven framework is proposed for the quantitative evaluation of building seismic resilience and repair scheduling with repair resource constraints. First, a calculation method for the post‐earthquake residual functionality of buildings based on engineering demand parameters is proposed. Second, the repair‐scheduling unit (RSU) concept is proposed for city‐scale repair scheduling. Moreover, two repair priority indices are introduced to evaluate the repair priority of each RSU. Next, the concept of job block is proposed to compute the repair time of an RSU with insufficient repair resources. Subsequently, the workflow of repair simulation is presented to calculate the community recovery curve and resilience index quantitatively. Finally, 68,930 residential buildings of Beijing City's 16 administrative districts are simulated to demonstrate the proposed method. The outcomes of this work are expected to be a useful reference for building seismic resilience evaluation and repair scheduling of communities. Consequently, it could be an aid to pre‐earthquake disaster risk reduction planning and post‐earthquake rapid recovery of building functionalities.
