    Hi, I want to:
    1. Create element without weight in the model, how to define such element.
    2.How to reduce stiffness of element without changing the section

    In order to obtain an element with no weight you need to change, from material properties, the element density to 0. (go to Manage–>Used materials–>select the material–>Mechanical Properties and set “Density” value to 0).
    You can impose smaller rigidity for an element in two ways:
    1.You can change material properties to a smaller value for longitudinaltransverse rigidity (go to Manage–>Used materials–>select the material–>Mechanical Properties and insert the desired value for longitudinal rigidity).
    2.Another way you can change the rigidity of an element is to select the element–> go to properties–> Cross section–> set “Concrete inertia type” to “Imposed value” and insert a value for “Cracked section inertia coefficient” as a ratio between desired rigidity and full rigidity (value smaller than 1).

    Thanks Vlad
