Streszczenie:

Failure criteria play a vital role in the numerical analysis of reinforced concrete structures. The current failure criteria can be classified into two types, namely the empirical and theoretical failure criteria. Empirical failure criteria normally lack reasonable theoretical backgrounds, while theoretical ones either involve too many parameters or ignore the effects of intermediate principal stress on the concrete strength. Based on the octahedral shear stress model and the concrete tensile strength under the state of triaxial and uniaxial stress, a new failure criterion, that is, the simpli

In this study, a typical mat foundation and structural loading pattern is considered. Three dimensional finite element analyses, PLAXIS 3D, is performed to determine the soil / foundation contact stress distribution, settlement distribution, distribution of modulus of subgrade reaction as a function of column spacing, stiffness of the soil and thickness of the foundation. A parametric study is performed to demonstrate the dependence of those distributions on various parameters. Moreover, a relationship between size of the foundation, deformation modulus of foundation soil and modulus of subgra

Abstract : Deterioration of concrete structures reinforced with steel bars can be seen daily in regions with aggressive weather as steel-corrosion problems worsen. Fiber-reinforced-polymers (FRP) reinforcement has proven its feasibility through different civil structural elements.

Deep Mixing involves the introduction of cementitious or specially formulated solutions directly into the ground through the use of purpose built blending injection augers. The system is mainly designed to increase strength and reduce compressibility of treated soil. In the first stage of the research effective mixture ratios and mixture types of stabilizing agents were investigated for soft clays (CL form Eymir lake and kaolinite) by means of unconfined compression (UC) tests on stabilized soils. The unconfined compressive strength (UCS) values were obtained for 7,28,90 and 365 days of curing

However, cold-formed steel buildings must be designed with adequate Fire Resistance Ratings (FRR). Hence cold-formed Light gauge Steel Frames (LSF) are assembled using channel sections and lined with fire resistive plasterboards to provide load-bearing wall and floor systems. There is an industry need to develop LSF floor systems with improved FRR. Adding multiple layers of plasterboard to increase the FRR of LSF floor

碩士<br>中原大學<br>應用數學研究所<br>106<br>The stress strength model that the probability that one component is greater than the other one in a system has been widely applied in many fields is of interest. We consider the Bayesian analysis of the inverse Rayleigh distribution (IRD). Different from the frequentist''s view, the stress strength P(X>Y) is viewed as a random variable. The Bayes estimate of this stress strength is then approximated by the Monte Carlo Markov chain of the probability, which is outputted based on its theoretical maximum likelihood estimate. We demonstrate the Bayesian a

The purpose of the proposed study is to examine the relationships among the strength of college students’ religious faith and positive coping behaviors (religious and non-religious) and their subsequent effects on physical and psychological well-being, perceived stress, and life satisfaction. Research has shown strength of faith to be positively associated with both mental health and life satisfaction, which in turn, are often related to better health (Larson et al., 1992; Ellison, 1991). Positive religious and non-religious coping behaviors have also been shown to have similar relationships w

Streszczenie:

Stress-strain relations for unconfined and confined concrete are proposed to overcome some shortcomings of existing commonly used models. Specifically, existing models are neither easy to invert nor integrate to obtain equivalent rectangular stress-block parameters for hand analysis and design purposes. The stress?strain relations proposed are validated for a whole range of concrete strengths and confining stresses. Then, closed form expressions are derived for the equivalent rectangular stress-block parameters. The efficacy of the results is demonstrated for hand analysis applied for deriving

An extensive amount of research has been reported in previous literature on the behaviour of FRP-confined concrete subjected to concentric axial compression. However, data on the behaviour of high strength concrete confined with various types and configurations of FRP systems is still lacking and no consensus exists on the complete response of FRP-confined concrete. In addition, no appropriate design guidelines are currently available. This thesis reports results from an experimental program involving 112 cylindrical concrete specimens, 88 of which were FRP-wrapped and the remaining 24 were

The application of high-strength concrete offers several advantages, such as reducing sizes of cross-section and material usage, increasing interior space, and minimizing production costs. However, there are significant differences in mechanics between high-strength concrete material and normal concrete in terms of their characteristics of materials. One of the examples is that high-strength concrete demonstrates brittle fracture after destruction. Hence, the origin

In light of the fact that column members placed below high-rise constructions bear relatively high vertical loads, the application of New RC with its high strength as well as the design without expanding cross-section of column members not only reduce material usage and costs but also increase interior space in a building. Currently, national studies related to New RC was conducted on the behavior of element levels, and little attention has been given to investigation into th

In order to evaluate a methane gas productivity of methane hydrate reservoirs, it is necessary to develop a numeric simulator predicting gas production behavior. For precise assessment of long-term gas productivity, it is important to develop a mathematical model which describes mechanical behaviors of methane hydrate reservoirs in consideration of their time-dependent properties and to introduce it into the numeric simulator. In this study, based on previous experimental results of triaxial compression tests of Toyoura sand containing synthetic methane hydrate, stress-strain relationships wer

Neben einer festigkeitssteigernden bzw. -abmindernden Wirkung ergeben sich ebenfalls große Unterschiede im Spannungs-Dehnungs-Verhalten. Zur effizienten Konzipierung von Betonstrukturen unter komplexen Beanspruchungszuständen ist daher die Kenntnis des veränderten Materialverhaltens notwendig.
