Summary When subjected to long‐period ground motions, many existing high‐rise buildings constructed on plains with soft, deep sediment layers experience severe lateral deflection, caused by the resonance between the long‐period natural frequency of the building and the long‐period ground motions, even if they are far from the epicenter. This was the case for a number of buildings in Tokyo, Nagoya, and Osaka affected by the ground motions produced by the 2011 off the Pacific coast of Tohoku earthquake in Japan. Oil‐dampers are commonly used to improve the seismic performance of existing high‐rise buildings subjected to long‐period ground motion. This paper proposes a simple but accurate analytical method of predicting the seismic performance of high‐rise buildings retrofitted with oil‐dampers installed inside and/or outside of the frames. The method extends the authors' previous one‐dimensional theory to a more general method that is applicable to buildings with internal and external oil‐dampers installed in an arbitrary story. The accuracy of the proposed method is demonstrated through numerical calculations using a model of a high‐rise building with and without internal and external oil‐dampers. The proposed method is effective in the preliminary stages of improving the seismic performance of high‐rise buildings.

“…De Matteis et al [160] carried out an extensive parametric study on the structural behaviour of T-stub joints showing that the material strain-hardening and the ductility considerably affect the strength of the joint. Brando et al [161] determined the ultimate capacity of the web in beam-to-column joints subjected to tension and adjusted the design criteria developed for steel joints by using correction factors that consider the mechanical characteristics of aluminium alloys. Recently, Adeoti et al [162] reported a study dealing with the flexural behaviour of hexagonal bolted joints underling the importance of considering all the parameters with great impact on the structural behaviour and stiffness in order to design joints with high performance.…”

“…While it is recognized that as-built joints provide some rigidity, the evaluation of the actual restraining action of semirigid connections is a challenging task. In this regard, the scientific literature provides several methos for estimating the real behavior of joints, including experimental characterization, numerical, analytical or mechanical models, Among the analytical methods, in order to reproduce the joint moment-rotation curve, the Component Method, a mechanical modelling approach included in Eurocode 3 Part-1-8 [4]- [6], is definitely one of the most reliable [7].…”

The paper investigates the influence of the actual behavior of beam-to-column and column base joints on the seismic vulnerability of one storey steel structures. A numerical study was conducted on as-built real steel buildings whose column bases and beam-to-column joints have a semirigid and partial-strength behavior, although they were originally designed as rigid and full strength. Finite element models of the selected buildings were developed, assuming both the theoretical and the actual joint behavior and their seismic performance was investigated through nonlinear time history analyses. Kinematic hysteresis models were assigned to semirigid joints to account for their actual stiffness, nonlinear behavior, and energy dissipation capacity. Then, fragility curves were derived, on both the theoretical and the asbuilt buildings, for various damage levels, with the aim of comparing the probabilities of exceedance of the selected limit states.
