The proposed paper compares tied-arch bridge alternatives and cable-stayed bridge alternatives based on needed load-bearing construction material amounts in the superstructure. The comparisons are prepared between four tied arch bridge solutions and four cable-stayed bridge solutions of the same span lengths. The sum of the span lengths is 300 m. The rise of arch as well as the height of pylon and cable arrangements follow optimal dimensions. The theoretic optimum rise of tied-arch for minimum material amount is higher than traditionally used for aesthetic reason. The optimum rise for minimum material amount parabolic arch is shown in the paper. The mathematical solution uses axial force index method presented in the paper. For the tied-arches the span-rise-ration of 3 is used. The hangers of the tied-arches are vertical-The tied-arches are calculated by numeric iteration method in order to get moment-less arch. The arches are designed as constant stress arch. The area and the weight of the cross section follow the compression force in the arch. In addition the self-weight of the suspender cables are included in the calculation. The influence of traffic loads are calculated by using a separate FEM program. It is concluded that tied-arch is a competitive alternative to cable-stayed bridge especially when asymmetric bridge spans are considered.

“…While the ratio of existing steel arch bridges in Japan has the rise to span ratio value distribution range from 1: 3 to 1: 9, mostly from 1: 5 to 1: 7. Very steep or very sloping ration values (close to 1: 8 or 1: 3) are usually applied to arch bridges with short span [2].…”

The purpose of this study is to obtain the optimum geometric design and cross section member element of steel arch bridges. It is necessary because the geometric design of the steel truss arch bridges have the direct impact to the steel section used in the structures. Therefore, steel section have the impact to the economic value of the bridge design due to the structure weight. There are many important variables have to considered in the bridge design. Rise to span ratio variable is the major variable in the arch bridge geometric design. Arch bridge structures rely on the axial force capacity of the main arch, whereas shear forces and bending moments as secondary consideration. The optimization process is done by collecting the axial force, shear force and bending moment data of each steel arch bridge numeric model, and scaling its value from 0 to 1 to compare the data of every span in the same field, in order to achieve the optimum rise to span ratio. Rise to span ratio data of steel arch bridges in China and Japan used as the comparison with the result of this study, due to their brief history and rich experiences on arch bridge engineering innovation, and also have the large of amount of steel arch bridges. The results of this study give the optimum value of rise to span ratio between 1/4 to 1/7. It has good correlation with the rise to span ratio data of steel arch bridges in China and Japan i.e. 1/4 - 1/6 and 1/5 - 1/7 respectively.

“…The performance deterioration due to corrosion and thinning with aging are also reported in the field of steel structures. Moreover, research and development related to repair and reinforcement technology of steel structural members are actively pursued in various countries [2,3]. It is desired that suspend the construction of repair and reinforcement should be carried out as short as possible.…”

This research is aimed to develop repair and reinforcement methods with excellent workability and usefulness for steel structural members that have been damaged through aging. Fiber-reinforced plastic, which has been used in various fields in recent years, is also used for building and civil engineering. Especially, it is assumed that carbon fiber-reinforced plastic (CFRP) has light weight and high-strength mechanical properties. Conventional methods of repair and reinforcement using CFRP are mainly hand-lay-up molding methods using carbon fiber sheet and adhesion methods using CFRP plate. However, both methods have some issues. Therefore, we apply the vacuum-assisted resin transfer molding to repair and reinforce steel structural members; the proposal of a construction procedure and a basic investigation of bond strength were carried out. In the basic investigation, a double-strap tensile shear test and a three-point bending test of steel/CFRP composite specimens were carried out. In the double-strap tensile shear test, in order to improve the adhesiveness of CFRP, the adhesive strength against shear force was compared between the specimen pre-coated with resin and a specimen not coated with resin after surface treatment. The results showed that the pre-coated specimen had high strength and stability. In the three-point bending test, bond strength and fracture mode against bending force were analyzed using adhesion length and number of laminated carbon fiber sheets as parameters. From the finite element method, the stress when peeling occurs due to the bending deformation was estimated and compared with the experimental result.
