چکیده
Preliminary testing in the laboratory has been used to investigate the interaction between the soil and a damaged rigid pipe under earth disturbance. The test geometry and measurement scheme to evaluate movement at fractures are described. Conclusions are drawn regarding the impact of the four 90 segments of damaged pipe on the deformation of the system when disturbed. The flexural stiffness of a rigid pipe with overloading fractures is similar to an idealized flexible buried pipe and simplified design calculations can be made using flexible pipe theory. RÉSUMÉ Des essais préliminaires en laboratoire sont utilisés pour étudier l’interaction entre le sol et un tuyau rigide endommagé sous des charges de sol. On présente la géométrie de l’essai et la grille de mesure pour évaluer le mouvement aux fissures. Des conclusions sont tirées concernant l’impact des quatre segments de 90o du tuyau endommagé sur la déformation du système quand il est chargé. Le module de résistance à la flexion du tuyau rigide avec les fissures est similaire à un tuyau flexible enterré et qu’une méthode simplifiée de calcul de conception basée sur la théorie des tuyaux flexible peut être utilisée.

Evaluation of Nonlinear Dynamic Response of Rigid and Semi-Rigid Steel Frames under Far-Field Earthquake Records
The purpose of this research was to evaluate the nonlinear dynamic response of rigid and semi-rigid steel frames under Far-Fault Earthquake Records. Accordingly, the fragility curve of the moment frames with rigid and semi-rigid connections was determined. Considering the analytical knowledge of structures in the past, the analysis and design of steel frames based on the assumptions of rigid or...
متن کاملNumerical Analysis of Composite Beams under Impact by a Rigid Particle
Analysis of a laminated composite beam under impact by a rigid particle is investigated. The importance of this project is to simulate the impact of objects on small scale aerial structures. The stresses are considered uni- axial bending with no torsion loading. The first order shear deformation theory is used to simulate the beam. After obtaining kinematic and potential energy for a laminated ...
متن کاملAn Innovative Rigid Tray Technique as a New Alternative Matrix System for Buildup of Severely Damaged Endodontically Treated Teeth (A Case Report)
Direct restoration of severely damaged endodontically treated teeth (ETT) using available and conventional and current matrix systems is sometimes impractical and in some clinical cases is impossible. The aim of this paper is to introduce and describe a new matrix system based on Rigid Tray Technique (RTT) for dealing with such difficult clinical cases.

متن کاملIntroducing Padded Wall to Reduce Sloshing Induced Wall Pressure in Water Storage Tanks
Sloshing due to ground motion develops large pressure on the walls of water retaining tanks. This paper evaluates the efficacy of padded walls on the reduction of sloshing effects in rectangular water storage tanks subjected to ground motion. An analytical solution based on velocity potential function is provided to obtain the response of rigid and padded wall tanks in terms of the wave elevat...
