require fire tested details of floor cavity barrier, non ventilated, against curtain walling and concrete with a galvanized edge former on vertical face. Mace would like to replicate the tested detail on site and would like to see the fire test details as certified. Also does the test cover abutment against a vertical intumes...

Hi, I did a simulation with the same stress on stainless steel HAS-U A4 M24 and stainless steel HAS-U A4 M27. It comes out the M24 has better capacity than the M27. I was interested to know how can it be possible ? I was expecting to have M24 with less capacity than M27.

I would like to carry out a check for blockwork of compressive strength 10.4N/mm^2 with dimensions 440x100x215dp. However, the online software is only allowing me to put in a minimum value of 14N/mm^2 and will not carry out any calculations below 14 (See screenshot 1). How am i able to carry out a check for typical strengths o...

Hello, I am working on a connection between rock and a concrete wall. The two surfaces are not in contact with each other, but there will be a gap of 20 mm in between for an insulation layer, see attached picture. Is there a way, using the HILTI dirlled rebars tool , to verify the interface for shear? Shear will be only take...

I have your load tables for the HTB-2 Anchors. However, they are based on different thicknesses of Plasterboard. I have a situation with plasterboard on top of 18mm thick Plywood. Do you have load tables based on this, or similar. Also, what minimum centres can these anchors be fixed?

We are looking to install a machine in an existing industrial unit that previously had anchors in the concrete floor. Some of the locations of the anchors we would like to install are close to the remains of these previous anchors and holes. Is there guidance to determine if this is acceptable?

I am installing a series of steel brackets which are resin anchored along a single skin brick wall. Some of the anchors sit immediately below window openings. What are the minimum requirements in terms of distance between the anchors and the free edge of the brickwork. Can you install to the top course of brick? If not where c...

Please can you explain the implications of proceeding with the design of anchors using CBFEM in Profis where the results are very different to those calculated assuming a rigid baseplate? I understand that flexibility in the plate can result in significantly higher stresses than for a rigid baseplate in the anchors, concrete a...

Eurocode 2-4 limits supplementary reinforcement to 16mm - are there any documents that explain the reason for this? I have looked a lot and can't find anything. The limit is quite restrictive for heavily loaded anchorages (e.g. a mooring bollard) where even closely spaced 16s would be insufficient.

Hi,   The product literature for this product states it can provide protection to cables for 60 minutes.   We have a requirement for EI120 for emergency lighting in communal areas.   Is this a suitable product to use, and can this product achieve this timescale?   If so, what DFT level is required?   Many thanks Martin
