    Learning Exel VBA

    I am trying to learn and practise VBA coding. I am absolute beginner. I find most references and books written on this subject are written with financial people in mind and soon drop me in subjects like Pivot table etc which are not of my immediate interest. So I have given myself a very simple...

    Wind Moment Connection Portals

    I am getting some calculations to check for portal frames with 'Wind moment Connection'. These are single storey portals spans about 6m. The beams are being designed as simply supported. The moment at beam-column connection is being taken as zero for dead and live load, but only wind load moment...

    Urgent- Regarding Continuity in mullion/Aluminum profile of Curtain wall at support.

    Arbu As I see from your sketch the vertical load of upper mullion and glass will be transferred from the upper mullion to the lower mullion through the sleeve. Is that your intention? Once you have tightened the bolt in the slotted hole during erection, the silicon gap for expansion will be...

    Multi-storey masonry construction

    The requirements for new-build masonry construction in the UK for 5 or more storeys were laid out in BS 5628-1 Clause 37.1 Table 12 etc. These gave requirements for horizontal and vertical ties, key elements etc. But what is the situation in an existing multi-storey masonry construction which...

    Deep beam reinforcement and flexure reinforcement

    Thats right. The amount of reinforcement can be calculated by either method. But using deep beam theory the reinforcement should be spread in the whole of tension zone near the surface of the web rather than accommodate it on one or two layers in bottom only. There requirements were written in...

    Grinding of Fillet Weld

    Strength of fillet weld is calculated based on throat thickness x weld strength. Most works specifications mention that visible parts of the weld runs to be grinded without giving much detail. On a recent site visit I noticed that the weld has been grinded almost flush as shown in the attached...

    Intermediate Stiffeners in Plate Girders

    In the UK the intermediate stiffeners in plate girders are welded to the top flange and web of girders but not connected to the bottom flange. A gap is left between the bottom flange and the end of stiffener; as the sketch shows. This details is followed no matter if the deck is at the top or...
