    Wood post Cracks

    I designed a deck with 8x8 wood posts in Tampa, FL the posts are 15 ft apart with deck projection of 13.5’ from the house. Those cracks appeared and started to progress in the past 2 month since the GC installed the posts. I know these maybe a normal checking but i needed an opinion. Some of...

    Hollow section expansion bolt

    dhengr They are super exhausting! Designed a welded connection and the came back telling me that they don't have welders on site and they are not willing to hire one Designed a bolted connection and they told me its expensive option I actually suggested using stud bolts(nelson stud welding)...

    Hollow section expansion bolt

    The cantilever is 60" projected (cantilevered canopy outriggers) spacing = 48" cantilever HSS 3" x 1/2" x 1/4" End plate fillet welded at the end of HSS 8" x 6" x 3/4" Main HSS Beam is 12" x 6" x 3/8” Main beam is existing and the outriggers will be fabricated in the warehouse.

    Hollow section expansion bolt

    Hey I am designing a connection of cantilever beam with end plate connected to HSS Beam. The customer doesn't want to weld the end plate to the beam so I proposed the HSS expansion bolts it seems that these bolts are very expensive so they came back to me asking for different type of...

    Traffic signal steel structure

    I may have explained this in a wrong way (to be honest I did not know what exactly needs to be done ) It is actually a CCTV Camera pole with double arm (Height is 26ft and each arm is 12ft) when the client did performance test on the pole itself the vibration was too much on the arms and the...

    Traffic signal steel structure

    i am designing a traffic signal steel structure ( Pole height = 26 ft and the cantliever is 12 ft) the client is concerned about the vibration since they will install cameras on those cantlievers I am not sure what are the procedures to design such thing ? can anyone provide me an example or...

    ALLOWABLE DEFLECTION FOR CONTINUOUS BEAM

    I am designing a continuous steel beam per AISC360. The left side of the beam is cantilever with span of 156" (refer to attached image for beam statical system) Applied loads are Dead and Live Loads only. I am using Florida Building code TABLE 1604.3 to determine the allowable deflection for...

    LOAD COMBINATION-WIND LOAD

    I am converting the Velocity pressure to ASD before adding the pressure coefficients which depends on the shape and size of the building as you mentioned. I am doing so since the Velocity mentioned in ASCE7-10 and ASCD7-16 is V ultimate . Long story short, I convert the ultimate wind pressure...

    LOAD COMBINATION-WIND LOAD

    I am using ASCE7-10 and ASCE7-16. and usually I use ASD Load combination Wind Load is always multiplied by 0.6 Question: I am multiplying the qz(velocity pressure) x 0.6 to get q asd does that mean that I cannot multiply the wind load pressure by 0.6 while doing the load combination ? or...

    CONCRETE BRIDGE DESIGN STANDARDS

    Hey please see two attached photos of a concrete bridge being built next to exiting residential building. ( I don't want to mention the country but the wind speed is around 80 mph) since I am not expert in bridges design I need some answers to the following with some references please...

    Guard Rails Deflection Limit

    So Far the limitations I found for a 42'' x 52'' Guard rail : AS/NZS code: Min [H/60+L/240,1.18''(30mm)] Allowable deflection= 0.919'' ASTM E985 Section 7.2: Min(H/24+L/96, H/12) Allowable deflection = 2.29'' Florida Building Code: allowable deflection of cantilever = 2xH/120 = 0.7'' ICC...

    Guard Rails Deflection Limit

    Hey all I am designing a Guard rail in Tampa, Florida and I did a lot of research to figure out the Deflection limitations but couldn't find actual solid resource. can you please provide me the resource for the deflection limitation when I apply 50 PLF or 200 Lbs on the top rail or vertical post.

    Aluminum design-Allowable stress increase by 33%

    Hey all I am designing Curtain wall Mullions which got tested per ASTM E330 and my calculations are not matching the test by 33%? this is aluminum profile and I applied 1.65 as factor of safety per ADM 2010. is there any way that we will have to increase the allowable stresses by 33% ? also...

    Steel HSS Cantliever and END plate connection

    I Attached the STAAD Model I did so you can see what happened and what did I do so you can give me your feedback The line load is approx 10 Lb/in downward The stresses increased on the upper bolt row as seen in the model and the plate is not considered as 100% fixed connection. the...

    Steel HSS Cantliever and END plate connection

    Hi I am designing a cantilever HSS and due to architectural reasons the client want the beam to be on the edge of the End plate per this picture. I used STAAD Model to do 3D Free body analysis for this end plate with the HSS and there were no weird stress there. Is there any restrictions in...

    Curtain Wall/Storefront Thermal Analysis

    Hi All I am doing a research on Curtain wall/ storefront systems Thermal analysis. If you can help me with references to the below: 1-softwares to be used in thermal analysis of Mullios/Transoms with thermal breaks 2-Required tests to be done to make thermal evaluation of curtain wall systems...

    PE Liscence

    Thanks all for your replies. Ron , I already did the evaluation and my education met the NCEES and US standard and right now I am getting prepared for the FE Exam (April 2020). Thought, I am trying to find Structural Engineering Jobs in Tampa, Fl but no luck. May be I have to be more patient...
