Quantifying the out-of-plane response of unreinforced masonry walls subjected to relative support motion

The supports of out-of-plane loaded unreinforced masonry walls in buildings are subjected to a motion that is filtered and amplified by the building structure and, in some cases, can be significantly different from the ground motion. Moreover, because thes ...

Seismic analyses of the Double Closure Plate Sub-Plate for the ITER Electron Cyclotron Upper Launcher during the Vacuum Vessel baking scenario

Timothy Goodman, René Chavan, Avelino Mas Sanchez, Matteo Vagnoni

The Double Closure Plate Sub-Plate (DCPSP) was introduced in the Electron Cyclotron Upper Launcher (EC UL) design in order to minimize the openings exposing the interior of the Port Plug (PP) to the port cell; avoiding thus the near environment activation ...

Experimental investigation of steel building gravity framing systems under strong earthquake shaking

Dimitrios Lignos

Hybrid simulations were conducted to evaluate the system-level seismic response of a 4-story steel moment frame building and its gravity framing system through various levels of ground motion shaking. The experimental substructure examined in detail corres ...

Ductility reduction factor formulations for seismic design of RC wall and frame structures

Katrin Beyer, Matteo Zerbin

Seismic design of standard structures is typically founded on a force-based design approach. Over the years this approach has proven robust and easily applicable by design engineers and - in combination with capacity design principles - it provides a good ...

Effect of damping models on the simulation of seismic axial forces in a reinforced concrete bridge pier

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Manuel Jordan

Post-reconnaissance findings after recent earthquakes have shown that the effect of the vertical acceleration component of the ground motion can be more damaging than typically considered thus far, particularly in near-field regions where the ratio of vert ...

Evidence for structural damping in a high-stress silicon nitride nanobeam and its implications for quantum optomechanics

Tobias Kippenberg, Dalziel Joseph Wilson, Sergey Fedorov, Ryan Daniel Schilling, Vivishek Sudhir, Hendrik Schütz

We resolve the thermal motion of a high-stress silicon nitride nanobeam at frequencies far below its fundamental flexural resonance (3.4 MHz) using cavity-enhanced optical interferometry. Over two decades, the displacement spectrum is well-modeled by that ...

Earthquake-induced loss assessment of steel frame buildings with special moment frames designed in highly seismic regions

Dimitrios Lignos, Seong-Hoon Hwang

This paper discusses an analytical study that quantifies the expected earthquake-induced losses in typical office steel frame buildings designed with perimeter special moment frames in highly seismic regions. It is shown that for seismic events associated ...

Effect of Column Base Flexibility on the Hysteretic Response of Wide Flange Steel Columns

Dimitrios Lignos, Hiroyuki Inamasu

Recent experiments on wide flange steel columns subjected to multi-axial cyclic loading underscore the influence of the member end boundary conditions on strength and stiffness deterioration due to coupling of local and lateral torsional buckling. Field ob ...

Force–displacement response of in-plane loaded unreinforced brick masonry walls: the Critical Diagonal Crack model

Katrin Beyer, Bastian Valentin Wilding

This article introduces an analytical model to compute the monotonic force–displacement response of in-plane loaded unreinforced brick masonry walls accounting for walls failing in shear or ﬂexure. The masonry wall is modelled as elastic in compression wit ...

Ductility of adhesively bonded timber joints

Thomas Keller, Anastasios Vassilopoulos, Myrsini Angelidi

In the field of timber engineering, adhesive bonding remains a promising, though poorly developed, joining technique that may increase the structural stiffness and capacity of timber joints and structures. Selecting ductile adhesives may further allow to c ...
