Liquefaction and earthquake Liquefaction is an extraordinarly complex and potentially destructive phenomenon that can occur during a seismic event of significant intensity. The accelerations generated by a seismic event result in an increase in the neutral pressure of the interstitial water contained in saturated sandy soil. Figure 1 – Comparison between stable soil on the…
Are you an architect looking to simplify the process of geotechnical calculation and analysis? Do you need reliable tools to ensure the safety and efficiency of your designs? Let me introduce you to GeoStru, a leader in the field of geotechnical engineering and specialized software. Geotechnical engineering is a fundamental component of modern architecture. A…
Dynamic characterization is a crucial step in designing earthquake-resistant structures. Non-destructive geophysical techniques like MASW are used to predict the shear wave velocity and provide valuable information for site characterization, ground response analysis, and micro zonation mapping. Studies have shown that NEHRP, IBC, and NTC2018 provisions can be used to classify soil profiles based on their shear wave velocities.
The EN Eurocodes apply to the structural design of buildings and other civil engineering works including, geotechnical aspects, structural fire design and situations including earthquakes, execution and temporary structures. For the design of special construction works (e.g. nuclear installations, dams, etc) other provisions than those in the EN Eurocodes might be necessary. It is basically used in 27…
As in accordance with Eurocode 7 Part 1, the hen prediction of geotechnical behavior is difficult, so it may be appropriate to apply the approach known as the “observational method,” in which the design is reviewed during construction. This method is applied by following this procedure: limits of acceptability of the values of certain quantities…
Stability analysis of embedded cantilever retaining walls in seismic area is generally carried out by calculating a factor of safety against a possible mechanism of collapse. However, a more rational approach consists in assessing the performance of the structure in terms of accumulated permanent displacement (Fig. 1). Indeed, this approach is required by many national…
GeoStru software is used worldwide and is translated into many languages. Reliability, computation accuracy and ease of use are some of the strong points of our programs. The progress and updating of the software has brought many new features such as the integration of the GeoDropBox Cloud service: now within the programs you can synchronize…
