Intended Audience. Benefits to Attendee. The Attendee will learn how to determine the embedment depths and foundation pressures for many pole type structures, including signs, flagpoles, light poles and pole framed buildings. These pole foundations may be more efficient and easier to install than conventional spread footings in many applications. Course Introduction. Poles foundations are commonly used for sign, flagpole and light pole foundations and pole framed buildings. A design criteria for pole foundations is indicated in Section and Paragraph This criteria applies to vertical poles considered columns embedded in either earth or in concrete footings in the earth and used to resist lateral loads.

The backfill in the annular space around a column that is not embedded in a concrete footing shall be clean sand thoroughly compacted by tamping in layers not exceeding 8 inches in depth.

Related Projects.This section requires more stringent breakaway characteristics. Breakaway light poles rely on frangible transformer bases to provide the breakaway feature. The AASHTO specification provided for a similar change in momentum except that the test vehicle weighed 2, pounds. While providing the necessary frangibility, the base must also be structurally adequate to support the illumination pole for design wind speeds.

This model number is required to be incised on the base. No tolerances for these variables have been established. Whenever a pole is knocked down, the transformer base should be replaced even if it is still intact. TxDOT typically uses breakaway poles wherever possible, even when not required. Do not use shims or washers to level breakaway base, because this may change the breakaway characteristics of the base.

Ensure that the top of the concrete foundation is level. When relocating breakaway roadway illumination poles, Item requires a new transformer base to be installed.

The old breakaway base should be destroyed to prevent reuse. This includes breakaway poles installed by maintenance forces at new locations. Cities installing light poles or maintaining lighting systems on state right-of-way must abide by these same guidelines. Districts should keep city maintenance personnel informed of the different system requirements and the allowable uses of the various transformer bases.

The old and new transformer bases can be distinguished from each other by height and model number. The old bases are 20 inches tall, while the new ones are 17 inches tall.

Tests have shown that breakaway luminaire supports do not operate properly when the vehicle strikes the pole too high above the ground. Breakaway poles should, therefore, not be placed in areas where they are likely to be struck more than 28 inches above the top of the foundation. Limiting the negative side slopes to between roadway and luminaire supports should ensure acceptable striking height.

This will help to ensure proper operation of the pole and breakaway device. Search for the word or phrase:.POLEFDN is a spreadsheet program written in MS-Excel for the purpose of analysis of a pole foundation assuming the use of a rigid round pier which is assumed free unrestrained at the top and subjected to lateral and vertical loads.

Specifically, the required embedment depth, the maximum moment and shear, the plain concrete stresses, and the soil bearing pressures are calculated.

Since there is not a universally accepted method for pole foundation analysis, this program offers up five different methods of determining embedment length for pole foundations. The "Pole Fdn Czerniak " worksheet is the primary method emphasized in this program, since it provides the most detail in overall analysis. However, it does yield the most conservative embedment depth results of all the methods presented.

ST2, PaperMarch This program will handle both horizontally as well as vertically applied loads. The vertical load may have an associated eccentricity which results in an additional overturning moment which is always assumed to add directly to the overturning moment produced by the horizontal load. This program assumes that the top of the pier is at or above the top of the ground surface level. This program assumes that the actual resisting surface is at or below the ground surface level.

This accounts for any weak soil or any soil which may be removed at the top. The "Pole Fdn Czerniak " worksheet assumes that the rigid pier rotates about a point located at a distance, 'a', below the resisting the surface. The "Pole Fdn Czerniak " worksheet calculates the "plain" unreinforced concrete stresses, compression, tension, and shear in the pier. The respective allowable stresses are also determined based on the strength f'c of the concrete.

This is done to determine if steel reinforcing is actually required. However, whether minimum reinforcing is to be used or not is left up to the user. The respective allowable passive pressures at those locations are determined for comparison. However, it is left up to the user to determine the adequacy.

Since all overturning loads are resisted by the passive pressure against the embedment of the pier, this program assumes that the pier acts in direct end bearing to resist only the vertical loading.

The bottom of pier bearing pressure is calculated, which includes the self-weight of the pier, assumed at 0. Beam on Elastic Foundation Analysis.

We both hope to return. The service we received at all our locations was excellent and the free upgrades were much appreciated and very unexpected.

We absolutely loved the tour of Iceland. It was awesome to have everything booked and set up for us in advance, but doing the self-drive tour gave us a lot of flexibility about what we wanted to do from day to day. It also let us really see the country and experience parts of it that probably aren't normally seen by tourists. Booking through Nordic Visitor made everything easy and let us just truly enjoy the experience.

It has been a truly memorable visit and journey and I had always wanted to see Iceland. The trip was even more fantastic than I had imagined. I now have plenty of memories, photos and drawings to feed my work as an artist. Great trip, enjoyed the freedom of not having to worry about tour guides and groups while on the holiday, but having the luxury of someone with local knowledge make all the bookings and design the itinerary.

The annotated map was great, the phone a life-saver. You have fantastic customer service. Anita was very helpful leading up to our trip. After visiting her on our last day she was friendly and interested to hear about our experiences.

The holiday was for our 10 year anniversary so we wanted it to be something special, and it definitely exceeded our expectations. This group really covers the bases, from a supplied cell phone to wonderful hotels to a specifically designed map.

We were a bit overwhelmed at first, but within a day became comfortable with the language, the drivers, and the culture. We definitely needed that cell phone as our car became problematic, and although they did not need to change hotels for us, they were ready if needed. We loved the quaint places they had us stay, and it was obvious that they had visited the places before recommending them. Highly recommend this group for a problem-free tour. Everything went very smoothly and with great ease.

Being greeted by the chauffer and shiny black Mercedes in Copenhagen and driven to the Scandic Palace Hotel right in the city centre was a real treat. I am very glad to have chosen Nordic Visitor because you are based in these wonderful Nordic Countries and I wanted to experience local culture.

Many thanks to Cecilia for helping us to achieve this. The hotels chosen were lovely, and all the transportation worked without a hitch. You have a great team. Keep doing the good job. Excellent documentation, all tours were of a very high standard, in particular the guides. We particularly liked the attention to detail in providing us with glasses to watch the solar eclipse. A magical and unforgettable experience. Another visit to Iceland is not out of the question.

Fantastic tour would recommend to anyone.Pure electric car sales were the bulk of that volume with 208. We also predicted two disappointments for 2016: DS and Volkswagen.

VW has launched 3 new nameplates in 2016: the Sportsvan has outsold its rival BMW 2-Series by almost 3-to-1, the Phideon is more of an image booster than a volume model at 800 monthly sales, but the C-Trek is the most promising with 5. The American SUV brand could easily have been mentioned among our success stories of 2016, as it has sold well over 100.

That puts the brand ahead of Cadillac, which did get a mention as one of the most successful brands in China last year. But the reason for holding off and predicting even more success for Jeep in 2017 is the launch of the new generation Compass early this year.

The previous generation Compass (and Patriot) have been the best selling import models in China, and starting local production will only add to that success.

Absolutely, but not irrealistic. In its home market, Geely wants Volvo to become a full-blown rival to the German luxury brands Audi, BMW and Mercedes-Benz, but it has a long way to go in terms of volume.

This strategy intended to give those local companies the opportunity to learn from their foreign partners and help to the technology to develop their own brands and models. The best examples of such troubled state-owned automakers are FAW, Chery and SAIC with its Maxus, MG and Roewe brands. Lastly, Shanghai Automotive Industry Corporation has got Joint Ventures with the two largest manufacturers in China: Volkswagen and General Motors, but sales of its own brands Roewe, MG and Maxus were less than 300.

These brands will continue to gain market share at home, at the cost of their competitors who can sit back and rake in the profits by producing cars for their overseas partners. What are your predictions for 2017. Which brand or model do you expect to surprise or disappoint this year.

Let me know in the comments below. His daily driver is an Alfa Romeo GT 3. You can find all his articles Here. In a few year China will be able to end the mandate for foreign automakers to form Joint Ventures with local manufacturers if they want to produce cars in China and avoid the high import duties.

If they do this I easily predict the foreign automakers will absorb their local partners who are completely dependent on sales of foreign models. More perhaps a consolidation in SOE brands is due.
