Hello! I am looking to design a connection between a precast core wall & a metal deck concrete slab. The intention is that the metal deck concrete slab acts as a diaphragm to transfer lateral loads into the precast core wall. More specifically, the idea is to run shear dowels within the...

Hi guys, Is there any design example (in Eurocodes even better) to see how to analyze and design a retaining wall which is subjected to vehicle impact as well? I would like to see how the moments on wall and base are calculated as well as the pressure below the retaining wall base.

Hi, Is there a specific rule from Eurocodes about minimum depth of a pile cap? I am aware that the minimum depth of a pile cap is governed, most of the times, by the pile reinforcement lap for example if H25 then 40 x 25 = 1000mm (depth) However I found on internet the below suggestions: If...

Hi, I need to estimate the CBR value for the sub-grade of a ground bearing slab (UK based). What I have from my data is the modulus of subgrade reaction value k which is 0.015N/mm2/mm. How I translate this to a CBR value? Thanks!

Hi, If you had a few typical plans of a building that shows the location and dims of the RC shear walls (typically stairs and lift shafts), what kind of high level check would you do to see that the location and stiffness of the shear walls is acceptable? Obviously, I am not looking for a...

Hi, Can you please advise what's the applied pressure kn/m2 under the base will be at the attached sketch? It's the horizontal force to the wall that I am not quite sure how to include in the applied base pressure...

Hi, I have noticed that the Steel construction.org for low-rise (up to 4 floors) suggests a steel weight estimation of 50-60kg/m2 Considering that a steel beam is given in kg/m (say 40kg/m), how do we actually estimate the steel weight in kg/m2. Thanks

Hi, I currently design a retaining wall for a parklift system within a parking of a residential block. The parking is located at the ground floor, therefore the pit of the parklift will be approx. 2m below ground floor level, please see attached photo and retaining wall highlighted. I am...

Hi, I am looking to check the shear and bending capacity of the attached connection. The post is a balustrade fixed at the bottom free at the top. Therefore, it transfers shear and moment to the base through the proposed fin plate. The shear and moment is 5kN and 7.5kNm. The fin plate is bolted...

Guys, If we have a continuous beam with pins at intermediate supports and uniformly distributed load applied, that means that it develops over the intermediate supports moments. So, if the steel beam is supporting by steel columns (intermediate supports)and we want to show it as a continuous...

So, I do not have experience on the design of structural elements exposed to environment (thermal effects etc). I am currently looking the design of a steel raised walkway and the idea is that's its going to be restrained at the supports therefore no allowance for horizontal movements (i.e...

Hi, We have a kind of a debate in the office so it would be nice to listen other opinions around here: Would you consider that bracing is required at this jetty (see attached photo). By the looks of the connections look pinned, not moment connections...

Hi, What check would you normally carry out to a steel I-Section beam when a balustrade will be fixed to the side of a steel beam web? Obviously, the applied horizontal load to the balustrade will transform a moment to the steel beam. Is this a torsion check of the beam maybe? From my...

Hi guys. I have started to work for a project that includes a new staircase within an existing building from ground to first floor. I never been involved with a similar project and I am starting to scheme it. The stairs are precast so I am going to propose steel columns with landing beams...

Hi guys, Probably an easy question for you but I am bit confused here....So I want to specify an unequal angle and I am not sure which axis to take into account in order to calculate bending moment resistance and second moment of area for the deflection check. Please see attached sketch with...

Is there a free calculator for torsion and warping constant for a hollow rectangular section? Thnaks!

Hi guys! I have been asked from a client to specify an aluminium section instead of steel section. The reason of this is because aluminium is non magnetic and its going to be used in a physics lab. The aluminum sections will be fixed between UB roof beams. The aluminium sections will carry a...

Hi guys, Within my ETABS model, I got the ground floor & 1st floor and a mezzanine floor between them. As you can imagine the columns are modelled at each level but the thing is that I want to model the columns which are not within the mezzanine, therefore these columns will be long column with...

Hi, Is there any way to assign a linear support on ETABS? I remember doing it easily on TEKLA & ROBOT but I can't find how to do it on ETABS. Ideally I would like to achieve a support like is shown within the attached...

Hi guys, I am about to design a core wall and I am trying to validate by hand the ETABS Shear Wall design results based on Eurocodes. Within the Design Load Combinations for the Shear Wall Design, I choose all my ULS load combinations (i.e. wind leads,live leads etc). The thing is that I am...
