I need the calculations of slabs (roof, floor and access platform) of the pillars and the interiors and exteriors walls (the exteriors are only frames and glass). The calculations must be made for a CONCRETE structure. All calculations have to be done manually and automatically (Engineering software or other). I will send an example of this same house made by a teacher, I want something similar. Also i send a start of the exercise made by me. There is no need to do calculations for overloads of earthquake, wind or snow conditions.

I am building a storm shelter in my backyard. It will have a compact staircase from floor level in the home (2' crawlspace), access to staircase will be via floor trapdoor. Once down the staircase their will be a 20' hallway to the shelter. I want it approx. 400ft2. It needs a bathroom (shower not bath), a bedroom with a full bed and dresser, a kitchen (propane stove?), living room with couch, coffee table (50" tv wall mounted), storage room. There will be a in-floor safe in the bedroom. I want everything made out of reinforced poured concrete. The structure needs to be at least 10' underground to roof (10' of dirt above roof). I live in North Central Alabama. Power will be mains supplied with battery backup / solar on main house. Water will be mains supplied, storage tank integrated into shelter. Needs air ventilation system. I will be putting a vault safe door (normal door size) on the shelter entrance. I need a design, layout, 3d model, and structural blueprints.

We are looking for a one page drawing of some structural changes to the roof structure of a single story existing home in Austin, TX. There is a 17' x 26' room needing span calcs for a shed roof where the 17' is the span. There is a small room that has a faux (non-load bearing) vault ceiling being built. There is a load wall being removed and a recessed beam needing sizing.

Just looking for some opinions, I need to do two calculations. (1) metal plate spanning two ways, has riveted connections (100mm spacing) with the supporting beams therefore I am considered plate rigidly (fixed) supported all ends. Additionally the plate got T-section in one direction, I believe this stiffener helps in bending. (2) 2nd plate is an arch shape but spanning only one way again this one can be assumed as fixed at the support due to riveted conncetions. For the first plate I am going to use Pusher chart to calculate the maximum bending. other one will be analysed using the software which possible produce bending and axial force. Can I have some suggestions? For first plate - can I consider T-section as support? so I can consider the plate 1.2m x 1m, then should I check the T-section? what checks required, just bending ok? or bending and shear? please note load will be dispersed through 230mm concrete plus 200 surfacing above. How do we check the second plate? in both cases can we consider plastic capacity for ultimate limit state?

I'm doing a senior design project, which is design an academic building for Wentworth Institute of Technology. Please see attached for project details. Geotechnical considerations: - Recommendations for the type of foundation we must use in 5-6 story academic building. - Soil parent material - Depth to groundwater - Bedrock type - Bedrock depth - Boring logs for the site. Review this geotechnical information and how it relates to your project (i.e., foundation design, road work, grading, etc.). As part of the report, provide a topographical map of the site that includes the following information: - Site topography - Significant land features (wetlands, rivers/streams and other water bodies, existing roads, etc.) - Scale and orientation As you start your senior design project, you will immediately see that you need information on thesoils and bedrock that exist at your site. You will have to request the information you need from your "Geotechnical Consultant". But to start the process, you first have to do your own library research tofind whatever information there is for your site. At a minimum, your design team must find the sitetopography and the general description of the soils that are on the site. Now, having this initial information, you will position the structures and facilities that your group is planning. Based on thetopography and the neighboring streets and roads, and the wetlands or rock outcrops, where do youwant to locate your building(s), and parking lots and detention basins (if needed) also, where are the major utilities, particularly those affected by gravity. To start this process, your group should go the WIT library and search out the U.S. Geological Survey topographic plans (also called Quad or Quadrangle Sheets) for your site. Then, for sites in Massachusetts, look up the appropriate Soil Survey for the county you are in. Most counties are available in hardcopy, but a few are on-line now. Now go through the following steps: • Look for the air-photo map with your site and determine the soil units and boundaries for the land parcel you are going to develop. • Determine what the symbols refer to - the particular soil formation name. What type of soilisexpected? Getacopyofthedescriptionsforeachunitonyoursite. • What is the geological origin for each soil unit? You will need to know the geological originfor the soils. The variation of soils on the site may affect where you locate buildings and other facilities. • Determine the general engineering properties for the soils on your site by digging through thevarious tables. At a minimum you need to determine the gradation of soils and plasticity. How much passes the No. 200 sieve? What is the D10 and the Cu? What are the Atterberg Limits? What is the expected permeability of the soils? Are cobbles and boulders expected? • What other information is available on the site soils? Shear strength? Compressibility?

I need someone to create an origami model using the Rigid Origami/Oragamizer software developed by Tomohiro Tachi. I need it so that it can be used in grasshopper in Rhino3D. Here is the crease-pattern: https://www.flickr.com/photos/elelvis/3026378998/ And this is what it should be able to do: https://www.youtube.com/watch?v=NUuRLyfkkb4 Here is the software: http://www.tsg.ne.jp/TT/software/ Related links: http://courses.csail.mit.edu/6.849/fall10/lectures/L23_images.pdf http://www.curvedfolding.com/page/page/list http://www.curvedfolding.com/page/ori-ref https://www.youtube.com/watch?v=w6Pk2CV0mKE https://www.youtube.com/watch?v=rrLk1NkBRU0 p.s. If you think you could do this from Grasshopper alone, contact me and I will send you relevant links.
