During the last decade, a number of hysteretic models have been developed to simulate complex deteriorating mechanisms observed in steel components such that earthquake-induced collapse risk can be reliably assessed. Such models are typically calibrated wi ...
Nonlinear analysis has become an increasingly useful and important tool for evaluation, upgrade and design of structures for seismic resistance. However, despite steady improvements in analysis capability, most practice remains anchored to guidelines devel ...
Structural Engineers Association of California2016
Nonlinear dynamic (response history) analysis is being used increasingly in design practice for the performance-based seismic design of new buildings. In contrast to nonlinear static analysis, dynamic analysis requires more explicit modeling of cyclic resp ...
The addition of a layer of strain-hardening UHPFRC to an existing member in reinforced concrete (RC) has proven to be an effective method to increase the structural resistance and durability of concrete structures [1-3]. This paper is intended for structur ...
Steel concentrically braced frames inherently provide great strength and stiffness, and are widely used for seismic resisting systems in buildings. These include conventional buckling braced frames and buckling restrained braced frames. Although the latter ...
In the framework of Performance Based Earthquake Engineering (PBEE), assessing the inelastic behaviour of structures both at the global (force-displacement) and local (stress-strain) level is of priority importance. This goal is typically achieved by advan ...
Hybrid simulation can provide significant advantages for large-scale experimental investigations of the seismic response of structures through collapse, particularly when considering cost and safety of conventional shake table tests. Hybrid simulation, how ...
The present paper proposes an improved design of conventional buckling braces (CBBs) by introducing intentional eccentricity along the brace length. The proposed brace is named the Brace with Intentional Eccentricity (BIE). Due to the inherent action momen ...
International Association of Earthquake Engineering2017
A series of seismic tests were conducted on a 1½-bay by 1½-story special steel moment-resisting frame subassembly from the onset of damage through incipient collapse. These tests were conducted using hybrid simulation with substructuring as a mean to demon ...
The severe damage and collapse of many reinforced concrete (RC) wall buildings in the recent earthquakes of Chile (2010) and New Zealand (2011) have shown that RC walls did not perform as well as required by the modern codes of both countries. It seems the ...
