    Circular shaped foundation for wind turbines

    Hi all, For wind towers/turbines, a spread footing might be an option. It can either be rectangular or circular, yet in most cases I have seen so far (from colleagues and in the internet) circular sloped footings are used (smaller thickness as u go away from the center, like attached in the...

    Inquiry about "Fundamental Principles" of EC8 (No-collapse & Damage limitation)

    Greetings, all! Pardon if this seemed a bit basic question as I do not own such profound knowledge neither in seismic analysis nor the Eurocode. In the Eurocode 8, part 1, Clause 2.1 (1P) for the Fundamental Requirements states that structures in seismic regions shall be designed to fulfill the...

    2 Difference Level Slab on Beam

    You can model the beam as a spandrel beam (wall section, then assign a spandrel label to it) which requires you defining the two floors in two different levels. This is more close to what you called "real-life". Yet this is not the goal of structural analysis software and tools. "real-life"...

    How to model beam with 2 different slab level in Etabs

    You can model the beam as a spandrel beam (wall section, then assign a spandrel label to it) which requires you defining the two floors in two different levels. Or, you can just model them as one floor at same level as Gaurav Malya said. You may try both and let us know which worked the best for...

    Drift Capacities in ASCE 41

    To this end, can someone elaborate more please about the so called "deformation-controlled" and "force-controlled" actions? As I understood from ASCE41, deformation-controlled actions refer more to actions causing ductile failure (exceeding yield value of the member considered), so basically we...

    Generating seismic loads methods

    My answer is based on definitions given in Eurocode 8 (EN1998-1:2004)"Design of structures for earthquake resistance". You may check it for your reference. Generally, analysis can be either Linear or Nonlinear. For the linear analysis, there are two methods: Equivalent Lateral Force and Response...
