Book Nonlinear Finite Element Analysis of Reinforced Concrete Structures Subjected to Transient Thermal Loads microform

Download or read book Nonlinear Finite Element Analysis of Reinforced Concrete Structures Subjected to Transient Thermal Loads microform written by Cheng En Zhou and published by National Library of Canada = Bibliothèque nationale du Canada. This book was released on 2004 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results obtained from four numerical tests indicate that the proposed computational scheme and the implemented codes are accurate and reliable. The need to incorporate fire loads into reinforced concrete structural design has long been recognized, and the traditional design method for structural fire resistance has been widely practiced by engineers mainly because of its simplicity. To simulate the structure's response to thermal loads, this research develops and implements a 2D nonlinear finite element transient analysis for reinforced concrete structures subjected to high temperatures. The proposed computational scheme takes into account time-varying thermal loads, heat-of-hydration effects, and temperature-dependent material properties. Algorithms for calculating the closed-form element stiffness for a quadrilateral element with a fully-populated material stiffness are also developed. Then, the capability of a 2D nonlinear finite element transient thermal analysis is implemented into program VecTor2(c), a nonlinear analysis program for 2D reinforced concrete membranes.

This book was released on 2011 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: A stochastic finite-element (FE) framework is developed to investigate the deterioration of reinforced concrete (RC) structures subjected to multiple environmental stressors. This study identifies the key mechanisms and parameters that affect the deterioration of RC components. Among the involved parameters, those related to the concrete properties and diffusion characteristics are categorized as internal parameters, while relative humidity, ambient temperature, concentration of carbon dioxide, and surface chloride content are considered as external parameters. Further investigation of these parameters indicates that most of them have nonlinear time-dependent characteristics with mutual interactions. To model the penetration of corrosive agents into concrete, a series of coupled physical environments is introduced. Through the full-scale, three-dimensional (3D) models of RC components, the major physical environments are simulated based on transient field theory, and the extent of deterioration is determined using a recursive approach. The major mechanisms that cause structural degradation of deteriorating components are also studied. These mechanisms include early-age cracking due to the hydration process and temperature variation, deformations resulted from the mechanical loads, and cracking induced by rust expansion. From the FE analysis results, the state of crack propagation is specified at all time steps and the diffusion characteristics are adjusted accordingly. One of the unique capabilities of the developed FE framework is to integrate various sources of uncertainty in the estimation procedure. For a more accurate durability assessment of deteriorating RC components, both temporal and spatial uncertainties of the influential parameters are taken into account. For this purpose, non-Gaussian stochastic simulation techniques are employed and a set of large-scale stochastic fields is generated for both structural and environmental variables. Since material properties and boundary conditions of the developed FE models can be updated based on corresponding simulated fields, the robustness of predictions is significantly improved after considering various sources of uncertainty. The applicability of the proposed framework for the model updating and health monitoring of deteriorating structures is demonstrated through a number of corrosion scenarios. The suggested updating approach provides engineers and decision-makers with a reliable tool to assess the integrity of deteriorating RC structures, optimize inspection intervals, and choose the most appropriate maintenance actions.
