| From the point of view of engineering application, study on the structural configuration, design method, foundation style and project cost has been carried out in (his paper aiming at the problems in existence such as the small scale project but the large work hours etc.According to the engineering practice of many years, the basic method for standardization design of microwave tower which is adapt to variational height has been proposed in this paper. Research on the structural configuration, web members form etc. shows that the broken-line quadrilateral angle steel tower is the most feasible and economic structural form for microwave steel tower.Discourse upon the load calculation, internal force analysis and selection of member size have been put up in this paper and wind load has great effect on the microwave tower.Foundation cost has occupied a considerable great percentage in the total engineering investment. As an alternative of individual footing, pile is a perfect foundation style of microwave tower from the point of view of the structural performance and the saving of project cost. Especially in the project cost, the cost of pile is the 5 percent to 6.7 percent of total engineering cost, so pile has visible economic effect.Finally based on the analysis and comparison of the economic benefit from some aspects such as the structural configuration, web system and foundation style, this paper has brought forward the empirical formulae reflecting the relation of the weight and height about the broken-line quadrilateral angle steel tower, the rectilineal quadrilateral angle steel tower and tube steei tower, which have importance value for engineering designers. |
