▪

Permanent:
- Vertical load caused by the self-weight.

▪

Incidental:
- Wind load.

1.7.1

Self-weight

The load case consists of the self-weight of light pole which is provided by vendor and is attached in Annex
01. The load is tabulated below:

Wind load (WIND)

Wind load is applied on the exposed area of the steel structure with a design wind pressure of 1.25 kPa. The
design wind pressure of 1.25 kPa is calculated for a wind speed of 45 m/sec. The load on the foundation due
to wind is provided by the vendor and is attached in Annex 01. The load is tabulated below:

DESIGN CALCULATIONS
Introduction

After the evaluation of the working loads presented in Section 1.7, the reinforced concrete footing is
modelled in Prokon to check for strength and stability.
3.2

Design of footing

One reinforced concrete footing will be used to support the steel structure of light pole HMA 9251. The
forces considered at the top of the pedestal are the supports reactions in SLS (provided by the vendor). The
footing has been designed in Prokon.

The summary of the footing design for HMA 9251 is as follows:
▪ Footing size
▪ Footing reinforcement
Top reinforcement
Bottom reinforcement

: 2500 mm x 2500 mm x 1000 mm,

▪ Pedestal size
▪ Pedestal reinforcement
Vertical reinforcement
Horizontal reinforcement

: 1200 mm x 1200 mm x 1000 mm,

: T20 - 300 (both ways),
: T20 - 300 (both ways).

: 24 T20,
: T12 - 100.

Wind loading for a Duodecagon (20 sided) High Mast is in accordance with the ILE Technical Report Number 7, based on BS
CP3 Chapter V Part 2. In this Standard the Basic Wind Speed is the 3 second gust speed estimated to be exceeded only once in
50 years. The force coefficient Cf for a 20 sided polygon section with rounded corners from De Havilland wind tunnel
investigations has been found to be a worst case of 0.6 when "point into wind". Mean hourly wind speed factor is given in
Appendix A , Paragraph A1 for each Category.

Natural Frequency Calculation.

The Natural Frequency is derived from the formula given in the Netherlands Standard NEN 3850 TGB 1972., and is
equal to : Squareroot of (0.25 / Tip Deflection ) . The tip deflection is calculated under self weight assuming an
Elastic Modulus of 210 kN./sq.mm.
