Deep Q-learning agent for building earthquake resisting wall
Katrin Beyer, Qianqing Wang, Ketson Roberto Maximiano Dos Santos
The construction of dry-joint brick masonry that is subject to seismic loading can be modelled as a strategy problem wherein bricks must be laid to form a load resisting structure. To learn how to mount bricks while considering relevant engineering criteri ...
2022Latest findings on the behaviour factor q for the seismic design of URM buildings
Recent earthquakes as the 2012 Emilia earthquake sequence showed that recently built unreinforced masonry (URM) buildings behaved much better than expected and sustained, despite the maximum PGA values ranged between 0.20-0.30 g, either minor damage or str ...
SPRINGER2022Numerical simulations of retrofitting interventions on timber floors in unreinforced masonry
Katrin Beyer, Igor Tomic, Ivana Bozulic
Unreinforced masonry buildings with flexible timber floors are amongst the most vulnerable building typologies for seismic loading. Though flexible diaphragms play a role in the seismic behaviour of unreinforced masonry buildings, the impact of the connect ...
2022Development of Dissipative Steel Column-Base Connections for Steel Moment-Resisting Frames under Seismic Loading
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 ...
EPFL2021Fragility 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 ...
2021Seismic control performance of a three-story frame prototype equipped with semi-active variable stiffness and damping structural joints
This paper presents numerical and experimental studies on semi-active seismic response control of structures equipped with variable stiffness and damping structural joints. Such adaptive joints, which are comprised of a shape memory polymer (SMP) core rein ...
WILEY2021Rate-dependent model for simulating the hysteretic behavior of low-yield stress buckling-restrained braces under dynamic excitations
Buckling-restrained braces (BRBs) are often idealized with rate-independent simulation models. However, under dynamic loading, BRBs featuring low-yield point steel exhibit rate-dependency that may lead to appreciable amplifications of the BRB forces. This ...
ELSEVIER SCI LTD2021Seismic 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 ...
2020Seismic analysis of reinforced concrete walls typical for Colombian construction
During the life of a structure, this one will be subject to a large number of solicitations. The objective of the civil engineer is to understand the behaviour of structures when they are subject to actions to ensure that these actions will not lead to fai ...
2020Sensitivity analysis of fractal dimensions of crack maps on concrete and masonry walls
Assessing building damage after earthquakes requires a visual inspection of the damage, indicated by maps of the cracking pattern on walls, which could be standardized via automated algorithms. To quantitate this damage, fractal dimensions of these crack m ...
