Damage Processes

This work deals with an improvement of an anisotropic damage model in order to analyze reinforced concrete structures submitted to reversal loading. The original constitutive model is based on the fundamental hypothesis of energy equivalence between real and continuous media following the concepts of the Continuum Damage Mechanics. The concrete is assumed as an initial elastic isotropic medium presenting anisotropy, permanent strains and bimodularity induced by damage evolution. In order to take into account the bimodularity, two damage tensors governing the rigidity in tension or compression regimes are introduced. However, the original model is not capable to simulate the influence of the previous damage processes in compression regimes. In order to avoid this problem, some conditions are introduced to simulate the damage unilateral effect. It has noted that the damage model is agreement with to micromechanical theory conditions when dealing to unilateral effect in concrete material. Finally, the proposed model is applied in the analyses of reinforced concrete framed structures submitted to reversal loading. These numerical applications show the good performance of the model and its potentialities to simulate practical problems in structural engineering.

For an infrastructure construction located in marine environments, maintaining good durability for the structures always imposes serious challenges, especially for the structure made of reinforced concrete. Concrete exposed to marine environment may deteriorate as a result of combined effects of both physical and chemical actions from marine environment. Corrosion of the reinforced steel bars that are embedded in the concrete is the most serious problem. Therefore, a method to protect the reinforced concrete in the marine environment from damages due to material deterioration and corrosion is proposed in this study. The method is through the application of bentonite material by utilizing its very finely divided form so that the larger capillary pores in concrete can be filled up. In this way, the impermeability of concrete material can be enhanced and then improve the corrosion resistant ability of the material.

The role of religion in providing people spiritual stability and the necessity for conducting worships has increased the demands of religious buildings. Taoist religious buildings have a significant presence in Taiwan. With increasing environmental awareness and declining wood production, current constructions of Taoist buildings have shifted from using wood to employing reinforced concrete as building material. However, insufficient indoor lighting results in buildings requiring artificial lighting, which in turn leads to energy consumption. Therefore, a glass-based material Mazu temple is proposed to substitute wood and reinforced concrete material. The design consideration for building is illustrated in this paper. Furthermore, the illumination of the Mazu temple constructed will is analyzed and compared to a traditional Taoist temple building. The results show that the illumination of glass-based temple buildings is better than traditional temple buliding. Hence, it could reduce the require time of artificial lighting.

AbstractThe article presents problem of non-uniform foundation of structures in weak wet subsoil. The problem is illustrated with the case study of two-chamber-reinforced concrete water tank constructed in 1920s of 20th century, which cracked during construction. Under part of foundation, where the peat was found, the concrete piles were introduced.The results of five-year measurement of crack widths with crack gauges and geodesic measurements of vertical displacement of tank were presented. These results indicate that the tank is not stable and part of broken tank supported on piles is movable.On the basis of the presented data, the general conclusions concerning the non-uniform founding of tanks are formulated.
