Txdot design manual has a good example. It should be online.

Thank you to all.

Owner A is suing Bulder B. The street is higher. The drainage of the original contours show everything draining at an angle. The owner A never had any problems until the retaining wall from B was constructed. The new home B is finally finished. There are homes behind these homes. So basically...

I need valid documentation for court: this is the Case; A block that has homes on both sides of the street. One end is uphill and the other is downhill. Somewhere closer to the end of the block (downhill), a builder built a retaining wall and slowed down the runoff which in turn caused flooding...

Codes, books, ...etc state for an 8' wall a minimum distance for doors/windows from the corners or re-entrance corners is 2'-4". Is there anyway around that using full studs + sheathing the inside & outside with plywood with 3" o.c. nail spacing. For a distance of 12" or 16". Typical one story...

Thanks guys. All responses were helpfull.

Where can I find design examples, information and details for Tilt-up walls?

Off by coordinates. Lidar has coordinates of 1196096.8537, 16610769.2215 while USGS has 50661.2560, 241901.5558.

The lidar information was given to us in xyz format. I converted it using Geopak into .dat then .tin and got contours. However, when I tried to superimpose the contours with the USGS maps but they were way off. The USGS maps matched a file provided by the state. So I know the problem is with the...

How can we minimize the swaying of high decks without adding x-bracing. The x-bracing is in the way. The decks consist of wood members. The posts are 4x6.

I guess since the concrete slab will be poured around the columns, do I need something like an expansion joint around the columns?

I am designing a 3-story beach house. My question is the second and third story are being supported by piles that are embedded more than 20' deep in sand. The first floor garage will consist of reinforced concrete slab on grade foundation. Question: what type of material could be used between...

Thanks for the information.

I am replacing a bridge built in the 40's. I determined the Q's using HEC-HMS (scs method) and compared it to the regression equ. (both were close). I used HEC-RAS and analyzed existing condition and proposed condition. The problem is the existing condition showed W.S.=79' while FEMA is showing...

I have a different experience with HEC-HMS. I had the training. I liked the software. Once I completed the training, I had a better understanding on how to use it. Only problem I have is, I do not agree with the results I am getting. The Q's are too big. However, I think this problem could be in...

Anyone know of a software to design a reinforced concrete slab-on-grade foundation?

Question, I have a topo that extends 500' left and right of the centerline of a creek. Is it accurate to import a USGS map and add the highest point with that elevation from the USGS map on to the cross-section for HEC-RAS. In other words, if the elevation from the sides of the creek...

Jae, Thanks for the reply. The interior wood beams and joists are rotted and had to be replaced. The interior piers are shallow piers (blocks). The exterior is a concrete perimeter beam that was supported with footings. In 1995 new drilled shaft piers approx. 10' deep were installed...

Regression equations in our area (South Texas) resulted in unrealistic Q's. We have been monitoring bridge structures with different frequencies. Reg. Equ.'s indicate W.S. elevations higher than bridge elevations at 25 and 100 yr frequencies, yet we have never seen those bridges go under water.

This is the situation, Pier & beam residence built in 1920. Concrete perimeter beam with drilled shaft piers (installed in 1995). The structure is a 1-story brick veneer with comp. shingles. We removed all interior beams, joists and piers. Now that it is all nice and open, the concrete...
