Thanks to Applied Science International for this great opportunity to present the paper "APPLIED ELEMENT METHOD FOR SEISMIC EVALUATION OF MULTIPLE SPANS OF EXISTING PRESTRESSED BRIDGE" at the World Conference Earthquake Engineering 2024.

https://lnkd.in/dFHEVCG9 our conclusion for the applciation of earthquake engineering starts from my research in Madrid with Manuel Pastor on the topic Manuel Pastor Dea Sota Giorgia Meloni

I am pleased to share our newest article on "Probabilistic assessment of seismic performance of slopes considering the sensitivity of sliding surface to input motion" recently published in "Soil Dynamics and Earthquake Engineering". The article is freely accessible until July 17, 2024: https://lnkd.in/gXBrgmnS

Modeling of Prestressed Bridge Subjected to Earthquake Loading and Pounding between Adjacent Spans The video shows the analysis results of a prestressed concrete bridge subjected to the 06.04.2009 L'Aquila earthquake (records AQK L'Aquila Aterno station). The multispan bridge presents severe degradation of the pier caps and girders. The girders were retrofitted with CFRP and External post-tensioning cables. The collapse initiates at the pier cap and evolves into the collapse of the entire structure. The bridge was not designed properly for seismic loads and pounding between adjacent spans was observed during the shaking. The work is part of a paper presented at the World Conference of Earthquake Engineering in Milan in 2024.

Check out the August 2024 issue of the Earthquake Engineering & Structural Dynamics Journal for our open access paper with my supervisor Michalis Fragiadakis: 📜 Title: "Probabilistic generation of hazard-consistent suites of fully non-stationary seismic records" 🔍Overview: A novel, computationally efficient, and practical probabilistic methodology for the stochastic generation of suites of accelerograms is proposed. The generated accelerograms are fully non-stationary, site-compatible, and have a target mean spectrum and variability. Specified correlation structure at pairs of periods can also be considered. Furthermore, two variants for the generation of suites of artificial accelerograms are proposed. The outcomes, in both approaches, are suites containing non-identical ground motion time-histories whose spectral mean and variability match those obtained from any of the usually employed target spectra in the field of earthquake engineering. 📄 Read the full paper here, DOI: https://lnkd.in/ds_W3-WC 💻 An online tool is available here: https://lnkd.in/dtpq-JVY #openaccess #EarthquakeEngineering #StructuralEngineering #ArtificialGroundMotions #StochasticProcesses #research

In earthquake engineering, the Response Spectrum plays a crucial role in understanding how structures react to seismic activity. Essentially, it shows the maximum response—whether in terms of acceleration, velocity, or displacement—of a structure modeled as a single degree of freedom (SDOF) across a spectrum of natural frequencies or periods during an earthquake. By studying the response spectrum, engineers can identify the specific frequencies that cause the greatest amplification of structural motion. This insight is vital for designing buildings and infrastructure that can better withstand seismic forces, enabling engineers to compare how different structures react to earthquakes. Ultimately, it serves as a guide for developing safer and more resilient designs. #EarthquakeEngineering #StructuralDesign #SeismicSafety #ResponseSpectrum #CivilEngineering #ResilientInfrastructure

A small part of our research around dynamical behavior of unsaturated soil entiteled "Assessment of matric suction effect on dynamic parameters of saturated and unsaturated sand and silt" was presented in 8th International Conference on Earthquake Geotechnical Engineering (#8ICEGE) in Osaka, Japan, May 7-10, 2024!💥 link: https://lnkd.in/d_ZtxWDw #unsaturatedsoil, #matricsuction, #shearmodulus, #dampingratio

【Assessment of Intangible Losses in Earthquake Engineering】 Full article: https://lnkd.in/gQAKPRVJ (Authored by Jaime García-Pérez, et al., from Universidad Nacional Autónoma de México (México), etc.)   The optimization of the total cost of losses caused by earthquakes is normally used to select optimal design parameters in earthquake engineering. This total cost is given by the sum of the initial cost and the damage caused by earthquakes. #Intangible_losses may be included in the latter. This paper develops the expression of the objective function in terms of the seismic design coefficient, calculates the intangible loss from both the individual point of view and that of society, and calculates optimum seismic design coefficients for a firm ground site. #Seismic_Risk #Optimum_Coefficients #Structural_Reliability #Utility
