摘要

对于运行时间较长或有扩容改建要求的服役输电铁塔，部分构件承载力不足将导致其无法满足更高的设计要求，有必要通过角钢构件加固来提升其承载性能。以输电铁塔中典型角钢为研究对象，提出输电铁塔无损加固方法，该方法采用螺栓与夹具使原构件与加固构件形成组合加固构件，组合构件对原构件不造成损伤，且结构简单、应用性强；建立细化的组合构件数值模型，研究原构件长细比、夹具间距（数量）、钢材特性对组合构件加固效果的影响，提出组合构件受压承载力计算方法。结果表明：提出的加固方法加固效果显著，加固水平最高达到56.34%；原构件长细比对组合构件受压承载力提升水平影响明显，组合构件的提升效果随着原构件长细比的增大而逐渐显著；当夹具数量为奇数个且夹具间距小于750 mm时，组合构件的加固效果最佳；加固构件的钢材特性对组合构件受压承载力和延性影响较小；提出的组合构件受压承载力计算方法与有限元模拟结果吻合良好。

Abstract

For the service transmission tower with long operation time or expansion and reconstruction requirements

the insufficient bearing capacity of certain components leads to the transmission tower unable to meet the higher design requirements. Therefore

it is necessary to study the reinforcement measures of angle steel components to effectively improve the bearing performance of transmission towers. Taking the typical angle steel in transmission tower as the research object

a non-destructive reinforcement method for transmission tower was proposed. In this method

bolts and fixtures are used to form a composite reinforcement component by combining the original component and the reinforcement component. The composite component does not cause damage to the original component

and the structure is simple while the application is wide. A more detailed numerical model of composite members was established to study the influence of slenderness ratio of original members

fixture spacing (number) and steel properties on the reinforcement effect of composite members

and the calculation method of compressive bearing capacity of composite members was deduced. The results show that the proposed reinforcement method has remarkable effect

and the reinforcement level is up to 56.34%. The slenderness ratio of the original component has obvious influence on the lifting level of the composite component

and the lifting effect of the composite component is gradually obvious with the increase of the slenderness ratio of the original component. When the number of fixtures is odd and the spacing of fixtures is less than 750 mm

the reinforcement effect of composite members is optimal. Steel properties of reinforced members have marginal effect on compressive bearing capacity and ductility of composite members. The proposed calculation method of compression bearing capacity of composite members is in good agreement with finite element simulation.
