    EZ-Shear Wall for ®ETABS v1.1

    Does anyone know where I can get a copy of this software which can design check shear walls by importing pier/spandrel forces directly from ETABS? The website www.structuralaps.com was referenced on another thread but it no longer exists. I would really appreciate any assistance in sourcing a...

    EZ-Shear Wall software

    thread726-396135 I wish to find a site where I can download a copy of the EZ-Shear Wall software referenced in this thread. The website posted, www.structuralaps.com, no longer exists. Can anyone help?

    Metric version of ASD Steel Manual Formulae

    Does anyone have a reference document giving the metric equivalent of the design equations used in the ASD Manual of Steel Construction?

    Roof Live Load - Temporary Portable Building

    What is an acceptable minimum roof live load requirement for a temporary office building (3 to 5 years)? Would 10 psf be acceptable??? The construction method is modular using timber framing on steel framed floor deck supported above grade on concrete foundation pedestals. These type of...

    J&L Hooked Bolts - ACI 318-05 Appendix D

    ACI 318-05 Appendix D allows the use of J or L hooked bolts and D.5.3.5 covers the equation used to calculate the pullout strength in tension. Is there a value for Abrg that can be used in D.5.4.1 for the side-face blowout strength of a J or L bolt? If so, how is it calculated?

    STAAD's footing design

    One point I would also add to Method 1 above. The foundation design allows a fixed value of 10% of the total axial load for the weight of the footing. The footing weight is not automatically calculated by the program. This is another reason why the second equation can lead to large foundation sizes.

    Pile Supports to Heavy Raft Foundation

    Consider the following hypothetical situation. I have a heavy reinforced concrete raft foundation pad, 400mm thick which will be constructed on a loose to medium dense sand. The Geotechnical Report recommends that the foundations should be constructed on piles to reduce differential settlement...

    Galvanizing for Marine Environments

    PeterCharles, As Rustbuster has already pointed out HDG normally involves a series of de-greasing, acid pickling, fluxing etc. before dipping in molten zinc. It is my understanding, that if the steel is shot blasted before entering the HDG process, the final thickness of zinc coating taken up by...

    Basement Floor Slab on Piled Foundation

    Thanks SuqlainUK and Andy for your comments. I think I will be going with Option 2. I have considered "watertight" concrete but because of the occupancy of the proposed basement area I will go with the fully tanked option to ensure no water leaks. Regards Mike

    Basement Floor Slab on Piled Foundation

    I am currently designing a 3 storey reinforced concrete structure over basement on a very loose sand/silt sub-grade. The Geotechnical Investigation Report recommends bored piles for the foundations. The basement of this building will be subjected to ground water ingress so I wish to tank the...

    Use of FLOAD Command in STAAD/Pro

    I have encountered a problem using the FLOAD Command in Staad/Pro 2000. If the Fload command is used using the YRANGE parameter only, the distribution of loads throughout the floor in question appears to be calculated correctly. However, if one uses the Fload Command to apply an overall floor...

    Traverse Spacing of Shear Reinf. in Wide Beams

    Thanks guys for your comments. On further investigation, it is also possible that the criteria for ties in columns as set out in ACI 318 ref: 7.10.5.3 could be adopted for traverse shear legs in wide beams. This approach is similar to the requirements set out for wide beams in BS:8110 where it...

    Traverse Spacing of Shear Reinf. in Wide Concrete Beams

    In ACI 318 I cannot find any direct provision for the traverse spacing of shear stirrups in wide reinforced concrete beams (1m +). The code only seems to refer to the standard longitudinal spacing of stirrups using 2 legs. Can anyone give me some guidelines on this topic? Regards Mike B-)

    Modulus of Elasticity of Different Soil Types
