In this paper, the dry solution for restraining the buckling failure of steel brace with the semicircle springs is presented. Finite element analysis shows that the effects of restraining the bucking of brace can be achieved if the structure of semicircle springs is designed appropriately.

In case of Enlargement method using Post-installed Anchors, mechanical expansion anchors were resisting tensile and shear force of Modular extension structure in exist building. The purpose of this study is to investigate strength of Post-installed Anchor on 16 MPa low strength Concrete under less than standard effective depth(hef). The fracture pattern of the specimens in Pull-out tests was pull-out failure and the strength showed 19% less than that of the design strength on test anchor manufacturer. In cyclic load shear tests the fracture pattern was steel failure of anchor and the strength showed 10% less value than that.

The SPC wall girder is connected to the vertical SPC walls to enhance performance of wall-wall girder connection. The fracture pattern of the SPC wall-wall girder connection was steel plate separation from concrete in SPC Wall. The purpose of this study is to theoretical analysis on fracture behavior of the SPC wall-wall girder connection under the monotonic load test inducing positive moment at connection. The Plastic hinge theory on steel plate of SPC wall girder is proposed to explain steel plate separation fracture pattern.

This paper is a aim to develop a connection modular-to-foundation that can be adapted using steel-frame middle & high-rise of the modular units. Analysis results, embedded column length is somewhat greater stiffness and strength were highly appreciated. Reduced embedded length even if the length of the base is not a problem for ensuring highly fixed.

Large span roof structures require an analysis of their static and dynamic behavior depending on the physical parameters defining the structures. Therefore, it is highly desirable to estimate the parameters from observations of the system. However, the study of the behavior of such structures shows the existence of critical parameters. A small change in such parameters causes a significant change in the motion behavior. In this paper we study the parameter identification problem for shallow sinusoidal arches considering damping effect.

The objective of this study is to analyse the dynamic stable and unstable behaviours of a space truss using an accurate solution obtained by the high-order Taylor method. Because numerical solutions can lead to incorrect analyses in the case of a space truss model due to the being parameters large, we analyse the solution’s behaviour using essentially an analytical solution obtained by the multi-step high-order Taylor method. In detail, the dynamic instability and buckling characteristics of the SDOF model under step, sinusoidal and beating excitations are investigated.

The development of QEA(Quantum-inspired Evolution Algorithm) and their engineering-problem applications have emerged as one of the most interesting research topics. These algorithms find optimal values with the operators such as quantum-gate by using quantum-bit superposed basically by zero and one. In this process, the balance between the two features of exploration and exploitation can be kept easily. So, this paper is to propose an optimum design program for truss system based on QEA and 17 bar plane truss model is adopted as numerical example.

Experimental tests on the steel grid composite deck were conducted for the evaluation of load transfer mechanism of deck joint which is composed of concrete shear key and high-tension bolts. The results show that the load transfer by concrete shear key is more dominating factor than the high-tension bolts.

Bending tests on the steel grid composite deck with the prefabricated joint were conducted for the evaluation of bending and failure behavior. The joint of deck is composed of concrete shear key and high-tension bolts. Test results show that deck with the joint has a larger load bearing capacity than continuous deck without joint, and the both decks have almost the same punching shear strength.

Dynamic analysis of PSC box bridge bearings for high-speed KTX train vehicles has been carried out to evaluate a running safety of train. Improved numerical models of bridge/vehicle and interaction between bridge and train are adopted, where bending and torsional modes are considered. Dynamic/static sliding distances of the bearings according to the KTX running speed are proved as a major parameter rather than the AASHTO and EN1337-2 focused on the distance by temperature variations.

In Korea, Because of excellent bending and torsional rigidity, PSC Box girder types have been applied to high-speed railway bridge in the most of the construction sites. But the introduction of a new structure types and materials is required in terms of diversity of landscape as landmarks. In this study, the latest high-speed rail bridge technology is investigated in terms of functionality and landscape.

This study reviewed analytically the behavior of Steel Plate Concrete(SC) walls subjected to axial forces to investigate the effects of shape and arrangement spacing of studs on the design of SC walls. In this study, it was proven that the inclined shaped stud resists more effectively to the bucking load than the general shaped stud in SC wall.

This paper deals with the response analysis of a floating building structure subject to both wind and wave loads. The hydrodynamic analysis is performed with sets of wind and wave loads selected from the 100-year return period concept to assess the effect of extreme ocean environmental loads on a floating building. From hydrodynamic analysis in time-domain analysis, it is shown that the responses obtained from the analysis in consideration of both wind and wave loads are far greater than those of wave load only.

Integral abutment bridges (IABs) have been used only as short to medium long bridges because thermal displacements of IABs limit the bridge length. One of recent studies regarding IABs showed the use of a spiral rebar can effectively control the crack propagations of the pilecap (Frosch, 2009). Accordingly, in this study, parametric study of spiral rebar on pile-to-pilecap connection were performed.

In order to lengthen the integral abutment bridge (IAB), pile-to-pilecap performance is one of the most important parts of the bridge since IABs have no expansion joints. Therefore, this study intended to develop four new types of pile-to-pilecap connections to improve the IAB performance using numerical analysis. Developed connections allow larger displacement and successfully control the crack generations.

Vehicle collision is one of cause for structural failure. The increased load carrying capacity of the truck is also a threat for existing structures. Recent studies show the actual shear capacity of the column of bridge is larger than industrial standards. In this study, truck-column collision model was developed and load carrying capacity of a column were evaluated.
