Bolt is 8" away from edge. I dont know a reason for 30 degrees, but this is an existing anchor installed at site. Does Hilti Profis design the anchors with bent or inclined shaft? I thought it only designs for vertical shafts.

Has anyone designed the pre-installed (L-shape/J-shape or) or post-installed (adhesive) concrete anchors with the bent shaft? Like the one shown in the image. Does anyone have the design calculation for this type of anchor that they can share...

@a_urbs - Can you elaborate little bit on post-tensioned collar approach? Is it the steel jacketing post-tensioned around the column?

Thanks for the response. @lexpatrie - The equipment cant be taken off from the columns. With equipment on columns, it is exerting the vertical loads on it. The cracks and spalls in top 1ft of column, I believe, is the result unreinforced concrete not being able to take the bearing loads...

The concrete column, 32"x 32", approx 8ft tall is supporting mechanical equipment (condenser). The are four columns such as this, supporting equipment. Each of these columns are cracked at top 1ft, some of them has 4" deep (horizontally)concrete chunks spalled off without exposing any rebars...

Thanks @AskTooMuch, I will check with Five Star or Sika if they can recommend any product. I think I will be able to manage with the embedment length of rebar epoxied into the concrete. Thanks @TLHS. I haven't used epoxy grout before so wasn't sure if than can be an alternative or not. But you...

@TLHS - The tanks sits on this slab (no pedestals for support), exerting bearing load on it. I don't expect any bending or other load than bearing. @AskTooMuch - The operation team wants to use epoxy grout instead of concrete for repair. I am trying to find out the reasons to justify that the...

Sorry for not giving the complete information. The intent to replace concrete with alternate material is to avoid long wait setting time of concrete.

I have a 2ft thick concrete containment slab for a lube oil tank. The slab has layer of rebars at top and bottom surface. The slab was exposed to the fire. The concrete from slab will be tested to determine if the concrete is deteriorated or not. My guess is that the portion of the concrete is...

Thanks for the response @HTURKAK. Would the grout bond with the concrete around to form a water-tight seal?

I have a 2ft thick containment slab, and we are coring the concrete samples from that slab upto its full thickness i.e. 2ft. How can I seal the cored slab to restore to its function of containment?

@dvd The channel is under the sprocket as shown in the attached image. The damage is at the middle of channel where the sprocket bearing sits. The sprocket gear that rotates the sprocket is attached to the side, as shown in section BB. The additional details of travel screen are shown here -...

Working on the traveling screen installed at the water gate where the water from sea comes inside the plant. The traveling screen has a rotating gear(called sprocket) which moves the connected screens as it spins. The gear wheel sits on channel beam at its mid span. The channel has failed as the...

I am trying to reduce the gage at MC 12x40 to 1.75in for a 5/8" A325 bolt. The workable gage is 2.5". How can I verify that the washers and nuts at the bolt holes will not overlap fillet radius of MC? Does maintaining clearance for tightening (C1) as given in Table 7-15 of AISC Steel Handbook...

I have a frame structure with exterior wall, so that the wind is resisted by the wall. If I were to model the frame in the software for analysis without modelling the exterior wall, then shall the wind load be applied linearly on the floor beam of the frame or it shall be applied as a point load...

Thanks @HTURKAK. Do you have a GTSTRUDL file where you have used a user defined sections and applied a code check command on it. If yes, can you please send it to me?

I want to use UPE and UPN channels from European Sections in GT STRUDL. The GT STRUDL has Table Name "U" for channels of European sections, which has some standard sections. However, the sections from "U" Table of GT STRUDL do not have similar sectional properties as UPE and UPN. Is there any...
