Hi Hilti Team, We are looking for a safe design using HIT-HY 270 HAS-U 8.8 M16 in a hollow normal weight concrete brick Hbn4 base material. The following are the design loads: Fx = 5.01 kN Fy = -5.14 kN Fz = -2.42 kN (downward) Mx = 0 My = 0 Mz = 0 We encounter pull-out failure and brick breakout failure even if the siz...

We are proposing using the subject anchor in a condition with infrequent vibration hence Nylock is being proposed. but we would like to check if there is any concern about the compatibility of Nylock used with the HY200/HAS-U anchor? If Nylock can be used, do you have recommendations for installation torque? In case Nylock c...

In Profis what anchor type do I need to use for normal 32 or 36mm rebar to check shear capacity in connection?

Can I use packers instead of grout when design stand-off anchors. If it is substitutable, what are the installation requirements to make sure the system is equivalent to stand-off with grout. For example, what is the maximum/minimum distance between anchor and packers. Is it necessary to put packers all around the anchor?

Can Hilti HIT-HY 70 be used to insert a chemical anchor into the top of 110mm wide solid clay brickwork wall as per the attached image, to resist shear forces only (brick breakout) and no uplift forces (pull out). And if it can, are the standard design capacity tables applicable. It is noted that the design tables say that a m...

I am trying to understand if sustained loads are included in the design of post installed bars in profits software. I tried to define two load cases with and without sustained loads and noticed that the utilization are the same. Please refer to the screen shot that i attached. Also I created separate reports for these two case...

I would like to be able to input a custom size for the flat bar geometry in order to replicate a custom web-cleat connection for a simple-span beam. Is this possible?

Hi. I'm looking to specify one of Hilti's A4 stainless steel chemset anchors to connect an aluminum pergola to a RC slab. Client is concerned about the existing waterproofing being penetrated but does the chemset provide watertightness? Or will I need additional consideration for waterproofing around the base connection.

The minimum anchor size can be selected in the PROFIS is M12. However size M10 can be find at Hilti website and technical data sheet. I am wonder if there is a way to select HST-3 M10 in PROFIS?

When calculating a connection that has a single anchor with a stand-off base plate without clamping with a shear force applied the check for pryout failure does not consider the effects of the moment due to the set-off distance (lever arm). However the check for steel failure does consider this lever arm. Why is the moment due...
