traffic signal pole is an important part of traffic engineering, is the traffic light way of structural support. In order to make the traffic lights of various natural environment have the effect of fixed uninterrupted, traffic light load should be considered in the design of the structure under the action of mechanical strength, stiffness and stability. At the same time, as part of the road traffic, road beautify station traffic lights should be considered in the design of function structure, the structure of the majestic, magnificent, and in harmony with the intersection building environment. The calculation method of traffic signal lamp pole has two kinds: one kind is the basis of the principle of structural mechanics and mechanics of materials, to simplify the signal structure of bar system; Another is to use finite element method (fem) 【 The finite element method ( 有限元法) Is a kind of highly effective, the commonly used numerical calculation method. 】 The approximate calculation method for checking the structure of the traffic lights light pole. Finite element method while the computer calculation accuracy is higher, but because of the limit state method can give enough accurate conclusion, and the calculation method is simple, has been widely used in practical engineering.

signal light pole upper structure for steel structure in general. Based on the theory of probability limit state design method, using the bearing capacity limit state and serviceability limit state. The lower base for the concrete foundation, USES the theory of foundation engineering design.
