Over the last two decades, global positioning system (GPS) technology has been developed rapidly and recently applied to civil structures for appropriate monitoring of structural performance. Currently, GPS technique can only be flexible having lower modal frequency ranges, it still remaining issues when comes obtaining accurate measurements. However, application is promising as a tool because measure dynamic characteristics static displacements in real time, whereas conventional using...
Due to the significant increase in age of infrastructure globally, maintenance existing structures has been prioritized over construction new structures, which are very costly. However, many facilities have not managed efficiently due a lack well-trained staff and budget limitations. Bridge management systems (BMSs) constructed operated globally maintain originally designed structural performance overcome inefficiency practices for bridges. Unfortunately, because most current BMSs based on...
In recent years, after Yoo queried the validity of Vlasov's equations regarding lateral buckling a circular arch, there has been number papers published with certain degree disagreement among various researchers. Based on comprehensive and consistent formulation curved beam theory presented in previous paper, closed‐form solutions thus obtained are used for comparison present theoretical study to others. major potential sources discrepancies traced, thereby rigor is demonstrated. Also, modes...
An extensive investigation on the buckling and large displacement behavior of thin‐walled circular beams has been conducted theoretically. Equilibrium equations governing linear, bifurcation buckling, have derived using principle minimum total potential energy. explicit clear approximation curvature effect is made in derivation process. The paper concludes with a series fundamental nonlinear that describe elastic curved beams. A companion examines closed‐form solutions for arch‐buckling...
Abstract The effects of frictional forces acting on the sidewalls buried box culverts are presented as determined with finite element method (FEM) and detailed soil modelling. possibility reducing earth pressure deeply concrete by imperfect trench installation (ITI) has been contemplated during last several decades. There have limited research results published primarily regarding qualitative aspect load reduction in ITIs. It was found course this study that significant develop along...
High-voltage transmission towers consist of structures that are designed to avoid the risk electric shock and prevent collapse. Hence, for efficiency, they generally as high-rise towers. The main tower posts primary structural members resist loads under various load conditions. Therefore, contribution secondary securing stiffness strength by reducing effective buckling length is an important one. However, we lack detailed member design criteria. In this study, observed effects horizontal...
A hollow reinforced concrete (RC) column has been used to obtain a more economical design by reduction of the material or self weight column. Although RC offers high effectiveness section properties, it may show poor ductility owing brittle failure at its inner face. In order develop and safer model for column, an internally confined (ICH) non-linear were proposed with considerations confining effects. To determine relation stress–strain in ICH possible modes investigated pressure was...
