Uncertainties in the Seismic Assessment of Historical Masonry Buildings

Katrin Beyer, Francesco Vanin, Igor Tomic

Seismic assessments of historical masonry buildings are affected by several sources of epistemic uncertainty. These are mainly the material and the modelling parameters and the displacement capacity of the elements. Additional sources of uncertainty lie i ...

Fragility Assessment of Beam-Slab Connections for Informing Earthquake-Induced Repairs in Composite-Steel Moment Resisting Frames

Dimitrios Lignos, Hammad El Jisr

Earthquake loss estimation in composite-steel moment resisting frames (MRFs) necessitates a proper estimation of the level of damage in steel beam-to-slab connections. These usually feature welded headed shear studs to ensure the composite action between t ...

Development of Dissipative Steel Column-Base Connections for Steel Moment-Resisting Frames under Seismic Loading

Hiroyuki Inamasu

In capacity-designed steel moment resisting frames (MRFs), column base connections feature a strong-base/weak-column design philosophy. Prior studies on fixed-end wide flange steel columns featuring seismically compact cross sections subjected to coupled a ...

Numerical Simulation of Unreinforced Masonry Buildings with Timber Diaphragms

Katrin Beyer, Francesco Vanin, Igor Tomic, Ivana Bozulic

Though flexible diaphragms play a role in the seismic behaviour of unreinforced masonry buildings, the effect of the connections between floors and walls is rarely discussed or explicitly modelled when simulating the response of such buildings. These flexi ...

Decay of Torsional Stiffness in RC U-Shaped Walls

Katrin Beyer, Ryan Hoult

Reinforced concrete (RC) U-shaped walls are a popular construction choice, commonly used to resist the lateral loads from wind and earthquakes. In many buildings, the center of stiffness of a floor is eccentric from the center of mass and the building will ...

Hysteretic Behavior of Moment-Resisting Frames Considering Slab Restraint and Framing Action

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady, Hammad El Jisr

This paper examines the influence of framing action and slab continuity on the hysteretic behavior of composite steel moment-resisting frames (MRFs) by means of high-fidelity continuum finite-element (CFE) analyses of two-bay subsystems and typical crucifo ...

Seismic performance of slender RC U-shaped walls with a single-layer of reinforcement

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Ryan Hoult

Reinforced concrete walls are commonly used to resist the lateral loading induced by wind and earthquake actions. While most walls include two vertical reinforcement layers, some regions of the world construct slender, non-rectangular concrete walls with a ...

Equivalent-Frame Modeling of Two Shaking Table Tests of Masonry Buildings Accounting for Their Out-Of-Plane Response

Katrin Beyer, Francesco Vanin, Andrea Penna

Equivalent frame models are an effective tool for the seismic assessment of existing masonry structures. Due to their simplicity, these models can be used to perform multiple nonlinear dynamic analyses, accounting explicitly for different sources of modeli ...

Simulating Cyclic Local Buckling–Induced Softening in Steel Beam-Columns Using a Nonlocal Material Model in Displacement-Based Fiber Elements

Dimitrios Lignos

Steel beam-columns subjected to cyclic loading (such as during earthquakes) may exhibit local buckling, which results in effective cross-sectional softening and localization of deformation. These phenomena are critical from the standpoint of performance an ...

Seismic design of non-dissipative embedded column base connections

Dimitrios Lignos, Hiroyuki Inamasu

Embedded Column Base (ECB) connections in seismically resistant steel moment frames are commonly designed to be stronger than the connected column, to protect them from inelastic actions. This relies on estimation of demands induced by the column and the s ...
