    Detection of buried foundations

    There are equipments/sensors used to for rebars detection. I hope it would any different types available which will help detect concrete or can use rebars as an alternative for concrete footings. But still you need to have specific dimensions details of the footing to approve or take any decision.

    Help solving this equation please?

    Yes, if you have a rigid joint you should account for rotational stiffness. Time is far more precious than you can imagine.

    Requirement of expansion joint in irregular Shape building

    I know the complexity a structure can be prone to, but you don't always have the choice to break the structure into separate components either atchitectural requirements or geometeric requirements. Time is far more precious than you can imagine.

    allowable settlement for substation equipment

    These type of equipments are not that sensitive to have any worst kind of effects in case your foundations are within the allowable limits. If you are worried or your substation Electrical engineer would discard your design when are having settlement of about 25-50mm depend on your type of...

    Requirement of expansion joint in irregular Shape building

    Well it should not be necessary but could be preffered to place expansion join, Incase you performe proper analysis to assess the dynamics of the structure by performing the required type of analysis as specified by your code. Time is far more precious than you can imagine.

    Compressive strength in ACI code is it related to Cylinder or Cube

    When it refers ASTM C39 which is based on concrete cylinder so you don't need to confuse youreself with cube strengh because cube strenght is refered in EN or BS Codes. ASTM C39 specify the compressive strength based on avg. CYLINDER testing of two 150x300mm or three 100x2000mm cylinder...

    Truss Multi-members connection at column support

    I had something on my mind, shown in the sketch below, 1. I don't think RAM Connection can handle this type of complex arrangment of different members connection 2. I don't think of it as that much complex, however i was more concerned with presenting to client in case he ask for calculation...

    Truss Multi-members connection at column support

    Hello Engineers, Have you ever design a connection of multi steel members connected as shown in the figure. Well the problem is not to make the calculations but how to make calculations quickly? What kind of calculation pattern/method would you like to follow to submitt calculation report in...

    Shear Wall Structural detail for Seismic design (special Boundary Element detail)

    There is a confusion about the designing and detailing about shear walls A 21 Storied Building has shear walls and moment resisting frame. Structural system selected as "Dual System", while analyzing the shear wall in a FEM software it requires "Special boundary elements" because the stress...
