    Core hole in masonry wall cut vertical bars

    We have a current project where the contractor cored holes through an existing masonry wall without locating the rebar first. As such when they cored the wall they also cut one vertical bar in each core hole. Now we need to fix the wall. What are cost effective procedures to repair this?

    Wind Load - Which method is correct

    Per the attached sketch and using basic statics you obtain different answers for the moment about A for an open structure. The sketch shows an open structure analyzed using ASCE 7-05. The method on the left uses a distributed load and then transfers the moment. The method on the right...

    Torsional irregularity - with no diapghram

    I am working on a canopy project that utilizes cantilevered columns for the sesimic resisting system. The canopy is simple structure - Steel column, steel beam, steel purlins, all supported on drilled peir foundation. There is no diaphram, all lateral loads are transferred through bending. The...

    Box Truss Column

    Easier questions than my previous one; I think. I design a lot of canopies and one thing I have been considering is going to a box truss for the beam and the column. This would be similar to that of the box truss members used for stage lighting and trade show displays. The issue with this is...

    I am looking for input on the Iyc value used in Eq. C3.1.2.1-14 in the 2001 AISI Standard for a C channel member with lips.. I have been taught it is simply the Iy published by the manufacture divided by 2. I am not sure if that is correct. Additionally I have seen other engineer’s calculations...

    DOUBLE CANTILEVERED BEAM EQUATIONS

    I am looking for some help in designing a double cantilevered beam. The member I am inquiring about is the beam on a "T" shaped structure and an "OFFSET T" structure. The structure is designed as a cantilevered column with a beam on top. The beam on the "T" shaped structure has spans equal in...

    Allowable Torsion Strees on Steel

    Any one know the allowable torsion on steel? I have a plate that will be subject to a torsional moment of 17,123.92 in-lbs and it is 11" wide. I am trying to size the depth. Any help on the process would be helpfull. I have never done torsion on steel before. Dustin

    Wrought Iron Properties

    Does any one know the current ASTM # and structural properties for wrought iron? Doing a guardrail system for a deck and I have never designed with wrought iron before, usually just wood, steel, and aluminum. I know the old number is ASTM A753 but do not know any more than that. Thanks for any...
