    Notes: The strengths of PFRP thin-walled columns are determined according to the modes ofbuckling which consist of local mode for short columns, global mode for long columns, andinteraction mode between local and global modes for intermediate columns. Unlike the local andglobal buckling, the buckling strength of interaction mode is not theoretically predictable. Refinedtheoretical approaches which can account for different elastic properties of each plate componentconsisting of a PFRP thin-walled member are used. Based on both the analytical buckling loads andthe experimentally measured buckling loads from literatures, the accuracies of Ylinen’s equation andmodified AISC/LRFD column design equation for isotropic steel columns were compared. From thecomparison, it was found that the modified AISC/LRFD column design equation is more suitable forthe prediction of the buckling loads of PFRP thin-walled members than Ylinen’s equations

    Notes: This paper presents the results of experimental and analytical investigations on thebehavior of GFRP pipes used in the water supply pipeline systems. The pipes consist of two filamentwound outer GFRP tubes and polymer mortar between the tubes. Parallel plate loading tests wereconducted and the test results were compared with predicted results. The load-deflection predictionwas conducted by the FE analysis and the conventional strength of materials approach. It was shownthat the results obtained by the experiment and analysis were agreed well

    Notes: The concrete-filled steel tubes have been widely used in buildings and civil structures.However the corrosion of the steel tubes results in the loss of load carrying capacities of the membersand, therefore, there is a need for regular maintenance. To mitigate such maintenance issues andprevent the loss of load carrying capacity, FRP composite were suggested as the candidate material. Anumber of research works has shown that the use of FRP tubes produced by filament windingtechnique was very effective on the improvement of compressive strength of the concrete-filled FRPtubes (CFFT). However the filament wound FRP tubes did mot contribute to the increase of theflexural strength of a CFFT. In this paper, a new type of FRP tube which consists of several pultrudedopen sections assembled by filament winding technique is proposed to improve compressive strengthas well as flexural strength of a CFFT. The load carrying capacity of proposed CFFT is discussedthrough the analytical investigation

    Notes: In this paper, the buckling behavior of elastically restrained orthotropic web plates isinvestigated. In general, the pultruded FRP structural member is composed of flat plate elements and each plate element is elastically restrained against rotation by adjacent plate components. For finding the local buckling strength of composite flexural member considering the elastic restraint at the juncture of plate components, the orthotropic web plate is modeled as an elastically restrained orthotropic plate under linearly distributed in-plane forces. For the derivation of buckling equation,the power series solution technique is employed. For the plate having different mechanical properties, the parametric studies are conducted by varying the degree of restraint along the longitudinal edge under compression. By using the results obtained, simplified form of equation is also developed so that the practicing engineers can evaluate the buckling stress of such a plate for the preliminary design of FRP flexural members

    Notes: This paper presents the analytical investigations pertaining to the elastic buckling behavior of orthotropic composite plates. By the pultrusion process the structural shapes composed of orthotropic plate components are readily available in the construction market. When the member is utilized for the flexure, lateral-torsional buckling and local buckling behaviors must be taken into consideration. In the local buckling analysis, flange and web local buckling analyses must be conducted in the design of such a member. For finding the web buckling strength, the bucklingequation for the orthotropic plate under linearly distributed in-plane forces is derived by using the Rayleigh-Ritz method. The boundary conditions of plate are assumed that the loaded edges are simply supported and the unloaded edges are simply supported or fixedly supported. The buckling coefficient of a plate having different orthogonal mechanical properties is found by using the numerical technique and the minimum buckling coefficient is suggested. In addition, simplified form of equation for predicting the minimum buckling coefficient for the plate is proposed. Brief discussion on the design criteria relating to the web local buckling is also provided

    Notes: The problem addressed in this paper is the elastic local buckling of thin-walled compression members whose plate components are tapered in thickness along the longitudinal direction. In the design of structural system in construction, shipbuilding, and aerospace industries, such structural plate components are frequently encountered. The elastic buckling analysis of transversely isotropic plates with varying thickness and various boundary conditions is performed to derive the buckling equation of thin-walled members composed of tapered plate components. In the analytical solution, the energy approach is adopted. The analytical results are presented in a graphical form in which the plate buckling coefficients are suggested with respect to the width ratio of plate elements and the degree of taper. In addition, using the buckling equations of plates with specific boundary conditions, the simplified form of equation for the local buckling coefficient of structural memberssuch as L-section, T-section, and Box-section is suggested

    Notes: The local buckling analysis of thin walled member is generally conducted by modelingeach plate component as an isolated plate with elastically restrained boundaries. When this analytical model is used for the orthotropic flexural members, it is necessary to obtain the degree of elastic restraint provided by adjacent plate. In this study, the equation to find the coefficient of elastic restraint by adjacent plate components of an orthotropic box-shape flexural member was derived by employing the energy approach, and the factors affecting the elastic restraint were briefly discussed. Using the suggested equation, the coefficient of elastic restraint was calculated, and the local buckling analysis was conducted according to the stepwise analytical procedure published by the authors. The theoretical predictions were in good agreement with results obtained by the closed-form solution. The local buckling strength of an orthotropic box-shape flexural member can be easily obtained through stepwise analytical procedure with the proposed equation that accounts for the effect of elastic restraint imposed by adjacent plate components

    Notes: The bridge deck is the most vulnerable element in the bridge system because it isexposed to direct actions of wheel loading, chemical attacks, and temperature and moisture effectsincluding freezing and thawing, shrinkage, humidity, etc. In 1980’s, several countries, such as USA,Japan, and Canada, already realized that the service life of the deck is critical for that of the wholebridge, and the research was initiated to develop new material and structural system to improvedeck behavior. In recent years, it has been encouraged to develop more durable, easily constructible,and more cost effective bridge deck than the current one in Korea. In this study, a concise state-ofthe-art survey of the experimental investigations on the FRP-concrete composite bridge deck underdeveloping in Korea is presented
