This paper presents a detailed study of the damages and collapses suffered by various masonry churches in aftermath seismic sequence Central Italy 2016. The will first be analyzed then compared with numerical data obtained through 3D simulations eigenfrequency nonlinear static analyses (i.e., pushover). main purposes this are: (i) to create an adequately consistent sensitivity on several defini...

In United States design practice, three system performance factors (R, Cd, and o) characterize the inelastic behavior of structures and are a crucial component of common elastic design methodologies. However, for steel-concrete composite frame systems these factors have been selected based on comparisons to more traditional and well-studied reinforced concrete and structural steel frame system...

To achieve better structural performance, lesser damage along with minimum residual displacements is a main objective of earthquake resistant design. In ordinary steel reinforced concrete frames, chances of severe damage because of the lower strength of conventional steel are always present during strong earthquakes. With the invention of high-strength steel (HSS) it can be anticipated that its...

The object of this paper is the evaluation of the seismic response of reinforced concrete frames designed according to the DDBD (direct displacement-based design) approach. The great part of research works about DDBD has been dedicated to planar frames, but recently also some proposals for 3D structures have been presented, in particular for wall structures. This paper will give a further contr...

The seismic design of bridge structure is influenced by the bi-directional excitation phenomenon. The bi-directional effects have been ignored in most of the past studies. The calculation of maximum isolator displacements (as per the equation prescribed by AASHTO) also ignores the bi-directional effects of ground motion. In the formulation, the coupled behaviour of the isolation systems has als...

Current concrete technology has made higher concrete grades more affordable to mid and high-rise buildings; hence its use has been increasing in the late years as it allows for smaller cross-sections, reduction of the structure’s weight, improve durability, among other benefits. However, it is known that brittleness of plain concrete increases with the strength; therefore, some national codes h...

This paper describes the prototype design, specimen design, experimental set-up, and experimental results of tests on three light-gauge steel plate shear wall (SPSW) concepts. Prototype light-gauge steel plate shear walls are designed as seismic retrofits for a hospital structure in an area of high seismicity and emphasis is placed on minimizing their impact on the existing framing. Three singl...
