So, got tired of subscribing to Autocad LT every year, thus trying draftsight, the free version. So far everything seems to work as in AC except the trim command with hatches. I’ve asked in the Draftsight forum, gotten no answers, looked in the DS help section, not very informative and done...
This must have been a typical situation in the last few years with the economy rundown. A project is designed, construction starts, only 2 structural shells are constructed -Rc walkups- and the project goes bust and the bank takes it. There is no construction activity for 7 years or so and the...
I am checking a wind turbine design which should comply w/ ASCE 7-05, Chapter 15. This type of structure does not correspond fully to the table that has the R factors for different types of structures. It could be 1 or 2 depending in how one interprets
the type description. If more than 50% of...
to class D or E if mitigated with the above procedures. ASCE-7 dwells into all the details for the specific seismic site evaluation for class F sites but I cannot find information on what you actually do after that evaluation and decide to mitigate the site, could it be reverted to class D, say...
If one were to check all the computations and drawings pertaining to a structure -non building- which is a very specialized one and that the analysis and design is rather proprietary, how would one go about the sealing of the drawings as the engineer of record?
The designer and manufacturer is...
Hi:
I have a question regarding thid progra, especifically for the Teng cohesion spreadsheet. At the bottom, schematically it shows the lateral pressure distribution along the pile as 9*c*D. c being cohesion, D pile diameter and the other is the number 9?. I wonder if that is right though I...
Dear colleagues:
I have a shear wall that has a Pu of -75K in what seems to be the controlling LC and a relatively low shear and moment in the order of 36k and 260'K respectively. Theoretically, this Pu is less than 0.35 Po and the other conditions set forth in section 1921.6.6.4 of UBC 97 for...
I am designing a build roughly 70'x 90'in plan with a 17.6'x 18' column grid with a perimeter concrete wall. It is basically a flexible mat foundation, so, control joints with cuts are not possible due to the continuos reinforcement needed in the slab.
There are thickened integral column...
I designed the deck 8 years ago for a building that has an underground parking level with a roof that is also used as a an open parking deck. The structural system beams run from east to west and are 4'wide x 1.5'deep including the slab. The slab runs north to south traversing the beams with...
