Abstract: An optimum management system building method of a network level based on life cycle performance and cost of infrastructures is provided to build the optimum maintenance management strategy of an individual structure level according to a given budget, thereby realizing a maintenance management system in advance. A maintenance management structure and a budget are built based on a project level of an infrastructure. Future budget establishment/repair and reinforcement/reconstruction priority are selected based on a network level about the entire infrastructure. The optimum management method satisfying a limited condition in a project level and a network level is built while repetitively performing the two steps. A budget by year becomes equal by repetitively performing the optimum process of the network level and the project level.

Abstract: PURPOSE: A bridge construction method using a composite girder for an arched bridge is provided to facilitate quality management, to improve the structural performance and constructability, and to improve the resistance efficiency against tensile stress of a girder concrete. CONSTITUTION: A bridge construction method using a composite girder for an arched bridge is composed of the steps of: arranging an upper tendon(300c) in both upper ends to be extended longitudinally; blocking out the lower edge of both ends inwardly; arranging a lower tendon which is an inner tendon(300a) and an outer tendon(300b) in the center end of both lower ends and both edge ends formed inwardly by the blocked-out unit to be extended longitudinally; pre-manufacturing an outer steel material(200) so that a lower tendon is exposed to the outside between both ends after passing through the both ends; manufacturing the composite girder by filling girder concrete through a hole for concrete of the outer steel material; inducing the first tension to the composite girder at both ends of the composite girder by using the first tendon which is an anchoring device, the upper tendon, and a center tendon; putting the composite girder whose both ends are supported on an abutment or a pier; forming a slab on the composite girder; and inducing the second tension to the composite by using the second tendon which is an anchorage device and the outer tendon in the both ends of the composite girder.
Abstract translation: 目的：提供一种使用拱桥复合梁的桥梁施工方法，以促进质量管理，提高结构性能和施工能力，提高钢梁混凝土拉伸应力的阻力。 构成：使用拱桥的复合梁的桥梁施工方法由以下步骤组成：将两个上端的上腱（300c）纵向布置; 阻止两端的下边缘向内; 在两个下端的中心端部布置作为内侧腱（300a）和外侧腱（300b）的下部腱，并且通过所述被封闭单元向内形成两个边缘端部以纵向延伸; 预制造外钢材料（200），使得下通道在通过两端之后暴露于两端之间的外侧; 通过填充梁混凝土通过外钢材混凝土的孔制造复合梁; 通过使用作为锚定装置的第一腱，上腱和中心腱，在复合梁的两端处向复合梁引起第一张力; 将其两端支撑在基台或码头上的复合梁; 在复合梁上形成板坯; 并且通过使用作为锚固装置的第二腱和复合梁的两端的外腱将复合材料引起第二张力。
