    Good book for programming computational geotechnical analysis?

    Hi! Is there some good book you'd recommend for implementing computer codes for numerical analysis (read: FEM, finite differences, and/or their relatives) of geotechnical analysis (specially topics related to buildings, such as: settlement, soil failure, slope stability, seepage, altering the...

    Usual English word for a building code replacing an older one?

    Hi! I'm not able to find what's the most common word in English to describe the act of an older building code being annulled by a newer code. In Spanish we say that the older code has become "derogado". Searching Wordreference, it suggests "repeal", "abrogate" or "abolish" as translations to...

    U-value of air? Why 25 W/m2K?

    I've been told to assume that the U-value of air is 25 W/m2K. However, in other calculations I'm using the thermal diffusivity of the same volume of air (2.208*10-5 m2/s at 30ºC), and, since both values are related, I'd rather prefer to obtain the U-value from the thermal diffusivity, so that my...

    About the energy equation for temperature in CFD

    Hi, I'm implementing a simple CFD simulator following the book "Numerical Simulation in Fluid Dynamics - A Practical Introduction" by Griebel/Dornseifer/Neunhoeffer and I was obtaining the weird behaviour that temperature was changing in the fluid just because of velocity gradients (I mean, the...

    The global cubes algorithm by Immel et al: Is it a particularization of discrete ordinates?

    There are situations where the overlap of knowledge and research between radiative heat transfer and radiosity confuses me. While radiosity (a computer graphics technique) was developed using radiative heat transfer as its base ground (acknowledged fact by the early/pioneering radiosity...

    How do you usually call each set of extra bars when doing curtailment of reinforcement?

    When extra bars from curtailed reinforcements are cut-off at different points, how do you usually call each "set" of extra bars that have the same length? "Set"? "Family"? "Bundle"? For example, at the picture above, would you say that there are three (sets/families/bundles/or what?) of...

    Is "development length" more popular than "anchorage length" in the US?

    Coming from Europe, I'm very used to the term "anchorage length" (and in fact I've never seen it called "development length" in my day to day environment). Now, reading some RC books published in the US, I see they tend to prefer "development length" (and... doing an Internet search, I even...

    RC T-beam: Conditions for limiting likeliness of lateral buckling

    The conditions shown above, meant for limiting lateral buckling in T-shaped beams, are from a very popular RC book in Spain, popularly known as the "Jiménez Montoya", where all terms are defined in the book, except for hs (hf is the flanges thickness, h is the beam total depth, bw is the web...

    How do you call the "chamfers" between web and flange in a RC T-beam?

    I'm trying to translate to English the term "cartabones", which we use in Spain for referring to the "chamfers" that are sometimes used between the web and the flange in reinforced concrete T beams. From the search I'm doing, it seems that these "chamfers" are not common in the US or the UK, so...

    Preferred term: Dimensioning, sizing, design?

    Hi, My education in structures was in Spain, and there we only have one word for referring to choosing all the dimensions and properties for a cross-section so that all Limit State requirements are met. That word is "dimensionamiento". Also, when we choose an initial cross-section for the...
