Can someone who has a review and comment copy of ASCE 7-16 tell me whether the requirement in Table 4-1 that decks and balconies be designed to 1.5 times the live load for the served area has been changed. The state of Washington issued an amendment to the 2015 IBC raising the live load for...
Here is a tough question for our crane design experts. The first few paragraphs are only background. The only question I have is at the end and it is specific to sizing the web stiffeners. I'd prefer not to make this into a complete lesson on design per CMAA #70.
I have a design for a 440...
I need a reference on how to calculate the the hoop and tangential stresses for a cone inside a tapered thick walled cylinder when you have a known tensile load between the cone and cylinder. I need to make sure the hoop stresses won't split the thick walled cylinder. The best example is...
Is there a function or macro that will tell me the number of days between any two dates. I have readings on several dates and am trying to get the average per day between those dates.
Thanks.
For any engineers who do structural engineering for Log Homes, Structures magagine March Issue put out by Structural Engineering Institute (SEI) has several excellent articles. It gives more insite into the upcoming ICC code and gives some recommendations on the seismic response value R to use...
Does anyone have a good reference for cinderblock design and details including reinforcing, door and window lentils, etc for high seismic areas. I usually tend toward poured concrete but I have some customers who really want a block foundation. I know they are used a lot in low seismic areas...
I have two 2800 gallon plastic AWWA certified potable water tanks. They are each 8 ft diameter and 8 ft high. The foundation is 6" of fine sand as recommended by the manufacturer. Total weight full is 8000 lb each. I am in seismic zone 3 and have 3 ft of stable sandy loam soil below with...
I am trying to get some other practicle opinions on how working engineers actually handle the lateral design of wood framed single family dwellings in seismic zone 2 or 3 areas. I have read several articles and papers on the controversy of designing walls for flexible diaphragm (shear load...
I am analyzing existing industrial buildings for seismic upgrades in Zone 3. These buildings have cranes. My question is what % deadload should be used for analysis and what is the reference. I checked ASCE 7, ASIE Technical Report 13 for construction of Mill Buildings, AISC Design Guide 7 Part...
