    Full Scale Grouting Test for LNG Vertical Tendon

    Hi All, ACI 376-11 in Clause 11.4.4.2 calls for a full-scale grouting test for PT Tendons. We have a LNG tank 46m high and would need to do a full-scale test (46m high) by building a mock-up sample and grouting it to satisfy code and spec. (140mm duct with 27 strand tendon). It seems a...

    Hollow core laid to a fall

    Yeah, I'm talking about varying the bearing height at each support. These are long spans (12m) and the topping would be too heavy over that distance if tapered.

    Steel formwork and finishes

    Thanks to all of you for your "prompt" replies. I originally posted the query 5 years ago. Since then we have built approximately 146,000m2 of residential and hotel accomodation using steel formwork. My experience has shown that it is better to use the spatter coat, although occasionally e can...

    Metal Escape Stairs

    Where I live all the fire escape stairs are concrete. I have noticed that in the US most escape stairs are made from steel. How do you justify the cost of steel stair and applied fire protection? Or do you have another technique to avoid fire protecting the metal? Newbuilder

    Stability of a Foundation

The same frame is designed as being fixed at the base, i.e. a moment is transferred to each footing. Does this footing...

    beam column junctions

    Nearly every beam detail I've seen anchors the top reinforcement at the support "downwards" into a column or wall. This often occurs with the bottom bars too. However, the contractors will cast the walls and columns to the soffit of the beam (and slabs). To avoid uneven construction...

    Welding Dissimilar Metals

    We have large stainless steel door subframe to be fixed to a rc frame. The detail calls for some kind of cast in fixing (which was not cast-in). The fabricator says that it is common to drill and grout some steel rebar dowels then weld them to the ss frame. Is this normal? Can ms and ss be...

    Lap Length of Reinforcement

    With reference to BS 8110 cl 3.12.8.13 Should the factors of 1.4 or 2 be applied to wall and column reinforcement? Is the wall or column surface "the top of section as cast"? NB
