In addition, the possibility to tailor the strength and stiffness characteristics by optimizing the winding angle gives the designer extra flexibility to design different pipe based on the different working conditions. In the current work, GFRP pipe designed with four different winding angles have been tested under internal pressure. Four pipes were manufactured by filament winding with winding angles of [±45/ ±45/ ±45], [±55/ ±55/ ±55], [±63/ ±63/ ±63], and [±63/ ±45/ ±55]. Each pipe has internal diameter of 110 mm, wall-thickness of 3.8 mm, and length of 450 mm. The pipes were exposed to internal pressure to determine their capacities. Under internal pressure, the maximum failure pressure recorded (60 bar) was that for the pipes with [±55]3 winding angles. All specimens failed in the same way of initial leakage, governed by matrix cracking, which causes a drop in the internal pressure.

Such studies involve application of results of climate models. US geological survey developed a web site [1] which provides visualization and access to global and regional (downscaled) climate data. In this study, results of three GCMs i.e. bcc-csm1-1m, HadGEM2ES and GFDL-CM3, each with RCP8.5 scenarios, have been applied to study changes in precipitation and temperature over Pakistan. The results of three models showed that temperature variation is expected to range from 1.5-2.35 C during 2025-2049, 3.23-4.48 C during 2050-2074, and 4.49-6.57 C during 2071-2095. Taking the average of the three models, this change is 1.89C, 3.82C and 5.49C for the simulated periods of 2025-250, 20502074 and 2071-2095, respectively, with reference to modelled values for the base period (1980-2004). The precipitation variation is expected to be 3.31%, 8.16% and 9.45% when worked as average for above three models during simulated periods of 2025-250, 2050-2074 and 20712095, respectively.","PeriodicalId":364849,"journal":{"name":"Seventh International Conference on Advances in Civil, Structural and Mechanical Engineering - CSM 2018","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115267797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although many domestic and foreign scholars from the field of geotechnical engineering have conducted theoretical researches on the deformation thereof at the present time, engineering formulas and empirical statistics cannot be solely applied to complex fractured bedrock with discontinuous deformation, as complex calculation and thoughtlessness can result in an error in model adaptability and calculation applications. Thanks to the development of Plaxis 3D, a finite element method (FEM) program, we are able to simulate complicated deformation issues in a non-linear model and to analyze the stress and strain thereof. By taking the “CM01 Construction Contract Project of Taoyuan International Airport Access MRT System extended to Zongli Train Station” as an example, this study simulates the ground surface settlement deformation induced by shield tunneling and compares the longitudinal and vertical deformation curves thereof with the results of on-site monitoring equipment. The HOEK-BROWN model is also adopted to provide more precise results than the traditional Mohr-Coulomb model. In the simulation of shield tunneling, it is a must to take the shield tail grouting, shield jack thrust force and cutter head pressure into consideration by having a rather stable longitudinal settlement curve. This helps to explore ideal simulations of bedrock tunneling, to which other projects with similar conditions can be referred.

However, waste heat from the engine is sometimes not enough to provide required heat to the vehicle heating system especially in cold countries. In such cases, fuel burner heaters are very often preferred and used. When the coolant temperature is too low, then its temperature increased by burning fuel on the fuel burner heater and heated coolant is then pump to heat exchangers, located inside the passenger compartment, so that heating comfort is achieved. However, this proses both consumes extra fuel as well as increases exhaust emissions left to the atmosphere. On the other hand, when full electric vehicles are considered, which are increasing their shares in the market at every other day, because there is no internal combustion engine, there is no main heat source also. Hence, required heat has to be provided form the vehicle main batteries or from any other energy sources like ethanol or diesel.

The equation establishes the relationship between dilatation, normal pressure and granular temperature. The granular temperature is defined as the sum of three elementary types of kinetic energy of particles in the course of its mutual displacements: relative shear movement, chaotic fluctuation and transversal mass transfer. The investigation was carried out by means of the earlier developed experimental and analytical method presupposing the distribution analysis of particles, falling from the discharge threshold of a rough chute. The profiles of velocity and fraction of the void volume have been determined in rapid gravity flows of modeling materials at simultaneous identification of the interrelationship coefficient of the granular medium state equation. The granular materials consisting of uniform spherical particles differing dominantly in roughness were used as model materials. It was found out the coefficient is equal to 10.3 for a wide range of the chute angle and the flow depth of smooth particles. The analogous coefficient value is observed for rough particles when the high chute angle or small bed depth take place only. However, the coefficient value increases more than four times for rough particles at high values of the bed depth and the chute angle close to the angle of repose of the material. This phenomenon is explained hypothetically by the effect of particle rotation.","PeriodicalId":364849,"journal":{"name":"Seventh International Conference on Advances in Civil, Structural and Mechanical Engineering - CSM 2018","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121791745","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
