There are many places in this world that are active 24 hours a day, 7 days a week—airports, shipping terminals, heavy-industry zones, expressways. To maintain safety, productivity and efficiency in those areas, high-mast lighting is critical. With high mast lighting, there is no substitute for experience. For many, that is where the engineering excellence ends.

Our high mast structures can be designed to reach heights up to feet tall, offer fixed mounting arrangements, and a provide a low-drag, internally wired fixture platform, which works with round or multi-sided shafts.

Ranging from 2 to 18 projectors, the system operates with 3 ropes or single rope and offers a high quality lighting experience. For the ENTI high mast poles there are basically two types, 3-rope type and rail type.

High mast lighting poles top system components are lift system rope pulleys, cable pulleys and top locking system. Lift: The platform where projectors are located can move on the pole. The projectors can go down to the bottom level of the pole for maintenance. Latch System: The platform to which projectors are connected is locked automatically on top of the pole. With the help of the locking mechanism, the load on the ropes goes out.

Solar warning light: It is the light which is located on top of the pole and when it becomes dark, it flashes. Lightning arrester: It is the stick on top of the pole in order to catch the lightning.

We usually use a drilled concrete pier for light pole foundations. You can model the pier in a 2D analysis program. Another proprietary program is "L-Pile".

Not sure where you can find it online. How can this issue be address when there is a limitation of the width of the foundation in the direccion of the moment Agree with JAE.

If possible, use a drilled pier. We usually hire a local Geotech Engineer to run L-Pile for us, and give us the required depth of the shaft and the shear and moments, then we design the required reinforcing.

Is there some reason a drilled pier is not possible on this site? If a drilled shaft is not possible, are drilled helical anchors an option on this site? Have designed a couple of sign foundations, where drilled shafts were not possible, using helical anchors as 'hold downs' on the edges of the footing. I agree with previous posts.Log In.

I would like to know of any good method to design a light pole 14' heigh over ground surface, 17" bottom diameter, and subject to a wind force of lb located at 11' over the ground surface. Do you know of any text book that contains good design examples of similar topics.

Uplift design on foundation and overturning due to wind forces. It can be a square foundation with two considerations: 1 Mass to resist overturning 2 Reinforcement for bending --or-- It can be a small drilled pier foundation designed for the same parameters.High Mast Light Pole Foundation Design is generally undertaken in the same manner as any concrete spread or pad foundation.

The principle is to make the foundation large enough so that the overturning moment does not exceed the maximum bearing capacity of the soil. As high mast light poles are standard fixtures they are often designed using standard foundation types which depend on the size of the mast and its location. The CivilWeb High Mast Light Pole Design Spreadsheet includes a unique High Mast Light Pole Foundation Design Spreadsheet which allows the user to specify a suitable high mast lighting foundation in seconds, from one of three typical high mast foundation design types.

The overturning moment depends on the height of the mast, the size and number of lanterns and on the location. High mast pole foundation design is usually based on the assumption that the underlying soil will not fail if the foundation limits the bearing pressure to a set value called the allowable maximum bearing capacity. The maximum bearing capacity of the soil is the pressure at which the soil starts to fail. This is a critical parameter and must be ascertained before detailed high mast lighting foundation design can begin.

This should be undertaken by a suitable qualified civil or geotechnical engineer. For preliminary design there have been a number of very general guidelines for the design of high mast pole foundations which include standard designs based on one or two assumed values for the allowable maximum bearing pressure. Below is one example taken from the Abacus High Mast lighting foundation design brochure.

These values are only for use in preliminary design and the bearing capacity must be checked with site measurements before detailed design is done. However this does give a handy guide for preliminary high mast light pole foundation design.

As described above for general and good soil conditions where there are no site specific restrictions on foundation size or depth, there are three main types of standard foundations commonly used for high mast light pole foundations.

This high mast lighting foundation type consists of an unreinforced block of concrete which resists overturning by mobilizing both the vertical and lateral bearing capacities of the surrounding soils. The mobilized soil pressures are illustrated in the below diagram.

To mobilize these lateral bearing capacities, this type of high mast light pole foundation can only be installed in stiff, cohesive soils. To achieve this the underlying soils are likely to be stiff clay or compacted sand or gravelly soils.

Care must be taken to ensure that any over dig is backfilled in such a way that the lateral bearing capacities of the surrounding soils is still able to be mobilized to resist the overturning moment. If the backfill is not suitably compacted and installed correctly it will not be able to mobilize the lateral bearing capacity of the surrounding soils and this type of high mast light foundation will not be appropriate.

The below table shows the required sizes for unreinforced passive concrete high mast lighting pole foundations to resist defined overturning moments.

This is taken from the Abacus High Mast brochure. This high mast lighting foundation type consists of an unreinforced block of concrete which resists overturning by mobilizing only the vertical bearing pressures of the underlying soils.

This type of high mast light pole foundation can be designed to accommodate any level of maximum bearing capacity. For this reason this type of foundation is often used in high mast foundation design when soil conditions are poor or unknown. However, for soft soils, clays and silts additional geotechnical advice is recommended to ensure that the high mast lighting foundation is suitable.

The below table shows the required sizes for unreinforced non-passive concrete high mast light pole foundations to resist defined overturning moments. This high mast lighting foundation type consists of a reinforced concrete pad foundation with a plinth which resists overturning by mobilizing the vertical bearing pressures of the underlying soils.

A standard detail drawing is shown below.

Similar to the non-passive high mast light pole foundation design, standard reinforced concrete pad foundations can be designed to accommodate any level of maximum bearing capacity.

The below table shows the required sizes for standard reinforced concrete pad foundations to resist defined overturning moments. Coarse aggregate size should be 20mm nominal. Cover to all reinforcement should be a minimum of 40mm. The concrete should be left for at least 14 days before any loading including the installation of the high mast light pole. Site specific ground conditions should be considered such as ground water level and any potential ground contamination effects.

A typical detail is shown below. The bolts should be tightened to the specified torque, as shown in the below table.
