Abstract Currently, there is no “timber moment frame structural system,” as the basic glulam beam‐to‐column connections (usually represented by bolted with slotted‐in steel plates) offer limited rotational stiffness such that they are usually treated pin connections. This paper proposes an innovative type of moment‐resisting connection reinforced long rods screwheads (LSRSs) and self‐tapping sc...

This paper presents quantitative information on the effectiveness of seismic retrofit solutions using bilinear oil dampers for seismically deficient existing tall steel buildings. For this purpose, a benchmark 40-story space moment-resisting frame building is studied that represents 1970s design practice in North America. Rigorous performance assessment based ASCE 41 recommendations reveals hig...

After Northridge (1994) and Kobe (1995) earthquakes, several studies have been conducted to improve the seismic performance of steel structures. In this investigation, new steel moment-resisting connections (FSFN) developed by the authors, were studied by the non-linear numerical analysis. These connections were single-sided beam-to-column assemblies that are representative of exterior beam-to-...

Progressive collapse is a condition where local failure of a primary structural component leads to the collapse of neighboring members and the whole structure, consequently. In this paper, the progressive collapse potential of seismically designed steel dual systems with buckling restrained braces is investigated using the alternate path method, and their performances are compared with those of...
