Hi all, I'm currently working on a project where I'm considering the use of a steel trapezoidal plate as the roof diaphragm for a single-story structure. If any of you have experience with this, could you please provide references, particularly concerning the horizontal shear aspect? Thanks !

Hi all, There seems to be really good sources/references for CLT diaphragm design/checks in the US but not in Europe. Does anyone have any good references that goes through all the checks for CLT diaphragm in-plane shear ? Thanks !

Hi all, I am looking for an experienced structural engineer minimum 15 years of experience in various materials & projects -preferably eurocode knowledge- to have as a mentor. I would like to meet online once a month for an hour. I am okay with paying for that hour. Anyone interested ? Thanks !

Hi folks, I have a relatively easy question for the more experienced structural engineers.. I have designed cantilevered balcony slabs for residential buildings in the past but have never done a cantilevered staircase landing for a public space, a school in this case. The location is not in...

Hi folks, Has anyone of you designed a reinf. conc wall which is terminating on the slab that is above a parking space so the walls are not terminating at the foundation. I would design the wall as a deep beam if I had any support points for the wall but unfortunately I do not have any beams or...

Hi folks, Do you guys consider smoothed tringular or trapezoidal load distribution , when you have a situation in which the load bearing reinf. conc. wall is loaded nonuniformly? For example there are line loads with different magnitude and there is a beam at one of the edges of the wall and a...

Hi all, I have a condition where at one end clt slab is bearing on a glulam beam and at the other end on a steel angle which is bolted to the precast wall. This is a pretty common detail. Normally I would not get worried about the eccentric load from the clt slab due to the steel angle...

Hi folks, I recently had a discussion about the shear load transfer in a massive timber diaphragm. Based on my understanding from the first principles, the lateral load, wind load in this case, should be transferred to the lateral resisting elements -> conc. shear walls in this case through the...

Hi all, I have a condition in one of my projects in which I need to terminate the conc. shear wall on the conc. slab that is above the garage (foundation floor). I have not done such a design before and I am not able to find any references or examples. Normally I assume a fixed cant. beam...

Hi Folks, I have a 6 story height RC wall/column that is taking only minor vertical load, not a big trib. area. I need to have some holes at each bottom corner of this element to locate precast landing connectors. These holes will be grouted after the connectors are placed inside of the hole...

Hi Folks, This is rather a theoretical question for the experienced structural engineers. How do you guys assume the shear wall load transfer and the bending moment reinforcement consideration at the ends of a shear wall when only a portion of the wall is directly sitting on the foundation wall...

Hi folks, I have a relatively easy question to the experienced structural engineers in the forum. Has anyone designed dowel connection between an existing RC shear wall and new precast reinforced concrete shear wall ? The idea is transfer horizontal shear through the dowel connection. The...

Hi Folks, I would like to hear back from those who have good sources for practical mass timber design (Glulam,CLT, Concrete & Timber Composite Slab etc. ) and detailing ( including firecases etc.- comprehensive ) ? Thanks!

Hi Folks, In one of my projects, I was asked to reduce the depth of a short(10inch high) concrete wall on which 2x12 stud wall is sitting. The depth of the concrete wall was originally matching with the depth of the studs but now the architect wants to decrease the depth with 2 inches, so...

Hi all, I am working on a project in which I will be using precast wall elements as a shear wall. I did some hand calculations to find out the shear in between panels (vertical and horizontal) and uplift. I just want to verify my calculations by modeling the walls as a plate element and connect...

Hi all, I have a relatively easy question to the experienced structural engineers in the forum. I have a 10” 6 story high RC shear wall , which is currently bearing on a 12” basement wall. The architect wants to reduce the basement wall from 12” to 10”. I would like to know what kind of...

Hi , I am designing a concrete beam- column rigid frame for a 5 story timber building to resist the wind load. I am not planning on having pinned connections at the foundation level so in a sense only the top & bottom of the concrete columns and beams are taking the moment. Is linear analysis...

Hi Folks, I have encountered with a regular situation for many but unique situation for me . I have a continuous concrete floor beam that is cutting/bearing perpendicular to the concrete wall's length direction , and another concrete beam connected to the continuous concrete beam so in a sense...

Hi folks, I have a rather seemingly complex but relatively easy question for the experienced structural engineers. I am designing 6 box shaped 6 storey buildings. The buldings are fully connected in between floors and also at the foundation level(raft /pile foundation). The buildings have...

Hi all, I have a steel frame that is approximately 23 ft high x 64 ft wide x 45 deep. The steel frame will sit on top of a concrete roof of a residential building. The frame consists of I beams and columns simply connected, and cable bracings at the center bays, and cable bracings at the roof...
