An extensive experimental program was carried out on compressive strength, flexural strength and tensile splitting strength of SF concrete. Seven concrete mixes with different proportions of SF were designed to produce 490 concrete samples. The probabilistic models to describe the variability of the mechanical properties of SF concrete were proposed. Two parameter probability models such as Weibull, normal, lognormal and gamma distribution were considered for the representation of variability. The probability distribution models were selected based on the three goodness-of-fit tests such as the Kolmogorov-Sminrov (KS), Chi-square (CS) and log-likelihood (LK) tests. The results obtained from the models are useful for description of the variability of selected mechanical properties of SF incorporated concrete. This study proposed lognormal distribution function as the distribution model that most closely describes the variations of different mechanical properties of SF concrete from a practical point of view. Further, the performance of typically selected buildings using SF concrete was evaluated through fragility curves and reliability indices incorporating the proposed probability distributions and variability of compressive strength property. It was found that 15% to 25% of partial replacement of cement with SF may yield better performance of the frames....Preview Download Preview +Other Building Technology project topics and materials you might be interested in»Causes of project abandonment in building construction industry and remedial measures»Causes of construction project failures and abandonments in Nigeria»Safety procedures and accident prevention methods in construction sites»Control of Noise Pollution and Sound Insulation in Buildings ( A Case Study of a Broadcasting Studio)»The implication and benefit of the use of softwares in building project construction (case study of selected software and firm)»Maintenance and servicing problems of specialist works in building»The effect of quality control in the building construction process (a case study of Afikpo, Ebonyi state)»A study of prospects and problems of timber as external material in building production in hot climate region»The impact of budgeting and budgetary control in construction project delivery in Nigeria»Challenges of low-cost housing delivery in Nigeria (Case study of Imo state)»Use of formwork design and construction of high building»Project planning and programming as tools for effective project delivery»The use of building survey for maintenance of building in Nigeria ( A case study of one storey building at Owerri, Imo state)»Design and construction of office complex for school of environmental design technology»Effects of labour management in building construction site - case study of Owerri, Imo state
