Client: What is the best method to do a forensic study for a settlement issue? Me : If you want to identify the soft or weak areas, I recommend using the MASW survey, which is a seismic method. Result: See below. The MASW (Multichannel Analysis of Surface Waves) method is an invaluable tool for soil settlement forensic studies. By evaluating ground stiffness and mapping subsurface conditions, MASW provides detailed information about the soil’s shear wave velocity (Vs). Using established correlation, we enhance the data to get SPT-N value This data helps in identifying variations in soil layers, detecting voids, and understanding the overall behavior of the soil. In this case, we found 4 anomalies of weak zone So what to do with this 4 anomalies? Let Geotechnical Engineer to decide. Question : Why using MASW not Electrical Resistivity? Perhaps I answer in the next post #Geoventure #YourIdealGeologicalPartner

Delving into this EQS article: Influence of Seismic Wave Type and Incident Direction on the Dynamic Response of Tall Concrete-Faced Rockfill Dams. 🔷 Authors: Chen-guang Zhou, De-gao Zou, Xiang Yu 🔷 Keywords: tall CFRD, wave analysis, vibration analysis, seismic wave type, incident direction, face slab stress 🔷 Key points: • The proposed wave-input method can incorporate the influence from the seismic wave type and incident direction in valley topography, which can be used for wave analysis and method improvements under complex topographic conditions or for other large-span engineering structures. • Seismic wave type and incident direction influence the extreme stress values and the stress distribution of a tall concrete faced rockfill dam, which is crucial for the identification of seismically vulnerable zones in the dam. • The seismic safety of concrete-faced rockfill dams generally decreases with an increasing incident angle, particularly when SH-waves arrive from the bank.

I do not recommend relying on Vs,30 as the sole parameter for characterizing soil type or for seismic design of structures. The recent earthquake in Türkiye, particularly the structural damages observed in Hatay province, underscores this limitation.

Here is the result of hardwork and teamwork.... 🎉 Successfully completed the 8th semester project on Analysis and Design of G+4 RCC Building ( for seismic zone V)

#EarthquakeRelatedPosts 9 𝐖𝐡𝐲 𝐃𝐨 𝐖𝐞 𝐂𝐚𝐥𝐜𝐮𝐥𝐚𝐭𝐞 𝐕𝐬,30 𝐚𝐭 30 𝐌𝐞𝐭𝐞𝐫𝐬? 𝐖𝐡𝐲 𝐍𝐨𝐭 𝐚𝐭 50? The average shear wave velocity for the top 30 m of soil, referred to as Vs30, is a critical parameter in earthquake engineering design. Most codes use Vs30 to classify sites according to soil type and evaluate seismic hazards; NEHRP, EC8. Shear wave velocity is vital for assessing the dynamic behavior of shallow subsurface soil. Site characterization for seismic hazard calculations typically relies on near-surface shear wave velocity values. 𝐖𝐡𝐲 @ 30 𝐦? • 𝐏𝐫𝐚𝐜𝐭𝐢𝐜𝐚𝐥𝐢𝐭𝐲: Boreholes generally provide reliable data up to 30 meters. Beyond this depth, data collection becomes more expensive and time-intensive. • 𝐑𝐞𝐩𝐫𝐞𝐬𝐞𝐧𝐭𝐚𝐭𝐢𝐯𝐞𝐧𝐞𝐬𝐬: Deeper boreholes may not adequately represent the dynamic behavior of the upper soil layers, which are crucial for seismic site response. • 𝐓𝐞𝐜𝐡𝐧𝐢𝐜𝐚𝐥 𝐂𝐨𝐧𝐬𝐭𝐫𝐚𝐢𝐧𝐭𝐬: Instrument limitations can make consistent and accurate measurements challenging beyond 30 meters. • 𝐑𝐞𝐥𝐞𝐯𝐚𝐧𝐜𝐞: Shallower depths (e.g., 20 meters) may fail to capture the site’s overall dynamic behavior adequately. Is VS30 an Effective Parameter for Site Characterization? What are your thoughts on using Vs30 for site characterization? #RekanDaho

I'm pleased to share our newly-published paper in #structural_Concrete journal. Regarding the significance of resiliency in bridges, #post_tensioned (PT) rocking piers with low residual displacements and minimal damages have developed over the past few decades. The #self_centering (SC) capacity in this system is provided through post-tensioning forces. Concerning optimum seismic design and retrofit purposes, it is essential to predict the actual degree of seismic damage and SC capacity of PT rocking systems after seismic hazards. In this case, a #self_centering_index (SI) is proposed to evaluate the SC capacity when piers are subjected to cyclic and seismic loadings. This SI, when used in co-operation with a viable damage prediction model, predicts whether or not the piers remain reparable under cyclic or seismic loading scenarios. https://lnkd.in/djTEaCr8
