Current Trends in Civil & Structural Engineering - Iris Publishers Nowadays, Ultra-High-Performance Concrete (UHPC) is being widely applied although there is a vital need to meet the design requirements. The bond stress between Ultra-High-Performance Concrete and reinforcing steel bars is a major issue which should be considered while designing the UHPC structures. In fact, there are some parameters such as UHPC strength, additive materials like Nano-silica content, concrete cover, development length and reinforcing steel bar size, which are the most effective factors on the bond stress between UHPC and reinforcing steel bars, therefore, the accurate design equations are required to consider the effects of all mentioned parameters on the bond stress.

Current Trends in Civil & Structural Engineering - Iris Publishers The road is the main instrument of urban thought and urban image. Since the existence of mankind, they have made some practices in order to reach the places they created. Transportation should be the first criterion for building a city. For this reason, the road parameter should be in one of the priority orders in the zoning areas both in the construction of new cities and in the process of urban transformation. There is a long-running process challenging a lot of planning standards for settlements area to be transformed. Urban transformation studies in the world have difficulties in accordance with international planning criteria because of the unlicensed and illegally built high rates in the existing risky areas and the number of the population residing in these areas which is considerably higher than the density value of the approved current plans. From 1950’s onwards, planning of urban informal settl...

Current Trends in Civil & Structural Engineering - Iris Publishers It has become imperative for a review of the subsurface engineering properties of the Lekki Peninsula due to increase in urbanization. The study focuses on the shear strength parameters and ultimately the shallow bearing capacity of the subsoil using the direct shear method. With methods based on CPT, SPT, Particle Size Distribution and Direct Shear Analysis, an underlying loosed sandy layer of about 4m thick overlying a medium dense sand was revealed. Plot from direct shear analysis reveals zero cohesion and phi values = 170 indicative of a loosed soil. This loosed property of the soil was also revealed by the non-peaked plot of the direct shear test and the particle size distribution plot. Based on correlation for non-cohesive soils using N-values, compressibility parameters for the loosed sandy layer (N values=5) indicates Elastic Modulus < 3500Kpa...
