    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...

    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-)

    Software for Wood Frame Analysis/Design

    As a follow on to the above items on wood design software I would like to suggest WINWOOD from Archon Engineering. This program is excellent value for money and is quite versatile. Trusses and beams are included along with connection design. The timber design modules in ENERCALC are also quite...

    Joint/Member Naming conventions

    Imagineer, In order to keep track to some degree of the nodes and member numbers I tend to divide my numbering systen into floor levels. Say ground level nodes numbered 1 to 99, first floor level 100 to 199, second floor 200 to 299 etc. The members can be numbered in the same way. I then...

    Restore a Tiled Dome

    JAE, I suspected that this was the case. The only thing I can think of other than a surface sealant is to try crack injection using a hyrophobic sealant. The injection process could take place from inside the dome in order to reduce the risk of damage to the tiled outer surface. Maybe a quite...

    Restore a Tiled Dome

    JAE, You say that the ceramic tiles cannot be removed. But can they be covered up? If a sealant is used must it be clear/transparent so that the visual tile appearance can still be seen? If the tiles can be covered over completely then I would be looking at either a mechanically fixed EPDM...

    Sealer for Existing Concrete Sidewalks/Pavements

    I propose to clean the surface of some concrete sidewalks/pavements using a Torbo Wet Sand Blasting System. The existing surface is dirty due to oil stains, bubble gum, ferrous oxide stains etc. What type of sealer product can I use to seal the concrete surface when cleaned? The sealer should be...
