    How can i intersect two planes in ACAD?

    I need help finding a way to intersect two planes in acad, apparently i cannot do this, i mean, ACAD only intersects solids. I guess i can do it the "old fashion" way which is obtaining equations of the planes and doing the rest of the mathematical stuff, but if ACAD has a way of doing this...

    Saturated Soil, Settlement Problem?

    We're building a shrimp hatchery in Nicaragua (Light Gage Stainless Steel Structure, Reinforced Concrete Tanks), the site is about 350 meters from the beach, today we ran into this problem, over the last week or so, we cut the area of work to remove the top layer of the soil (black mud, highly...

    Structural Abuse

    I was thinking about starting a new thread about something i thought it was stupid, but since i saw and read this thread i will place my question here. I work on a construction company in Nicaragua, a client who is going to be in charge of building a road called us and said he needed a...

    Rigid diaphragm?

    Structureguy, thanks for the observation, i had thought about it before. UcfSE, the building code used in Nicaragua is practically a copy of the Mexican code, the rigid diaphragm definition that appears on the Nicaraguan code, i'm almost 100% sure it's taken from the IBC. tngolfer, there are...

    Rigid diaphragm?

    Thank you all for the help, i realize they are both a little flexible, but what i really wanted to know is if they are rigid enough to transmit the lateral loads to the vertical elements, construction wise i believe figure #1 is easier to build, but i like option #2 because i thought it was more...

    Rigid diaphragm?

    I'm having trouble determining which of the two options represent a rigid diaphragm (pdf file attached), it is for a two storey house, using confined CMU walls, to me figure #2 is correct but i've seen both types of construction so i'm confused. For a brief explanation on Confined Masonry check...

    Industrial Facilities Roof System

    Thanks for your answers. I agree with you all that even with angles, the compression capacity of the brace is very limited, but for some reason i rather use them instead of rods, unless the span is too large, probably because rods can be tensioned in a more appropiate way, but if the braces are...

    Industrial Facilities Roof System

    I've noticed that the roof system used in industrial facilities (by industrial facilities i mean one story, large span frames), usually have braces at the roof level; i read on the book "Structural Concepts and Systems for Architects and Engineers" by T.Y. Lin & S.D. Stotesbury that these...

    Welded wire sandwich panel in ETABS

    Hello, i need a tip on how to model "welded wire sandwich panels" on ETABS, i'm not sure if anybody here is familiar with this system, but it's popular in Latin America, specially in Mexico. The structure that i'm modeling is a 2 story house, the lower floor walls consists of "confined masonry"...
