Abstract: A Submerged Floating Tunnel, also known as an Archimedes Bridge, may be employed at a number of crossings with a range of various conditions. However, the presence of considerable dynamic oscillations was threatened by swell, vortex shedding, and slowly changing internal waves caused by salinity-differentiated layers. In addition to these complex conditions, common incidental events like fire, sinking ships, falling anchors, and unexpectedly large amounts of water entering the tube must be avoided in all applications. The development of research in the areas of potential risk and influence of actors, risk index system, and risk level of SFT is of considerable theoretical and practical value when combined with the features of submerged floating tunnel (SFT) and the surrounding....

Abstract: The existence of cracks and deflections in a reinforced concrete structure is a matter of great importance and have been under study for many decades. In many cases, such cracks or deflections might represent a sign of danger to the structure. Hence, it is indeed important to accurately study and monitor the development of these cracks and deformations. In this study, two surveying techniques (Laser scanning and close range photogrammetry) have been used in addition to Linear Variable Differential Transformer (LVDT) to monitor the width of cracks in reinforced.....

Abstract: According to the requirements of eco-friendly concrete, this study investigates using of the waste materials: rubber aggregates (RA) and waste pigments (PPL) as partial replacements of fine aggregates besides partial replacement of ordinary Portland cement with silica fume (SF), metakaolin (MK) and fly ash (FA). A total of ten mixtures were prepared and cured in two groups: with natural water and sea water. Slump test and compressive strength test were carried out for all specimens. It can be concluded that the highest workability was obtained from the mixtures which contains SF as partial replacement of cement by 10% and those which contains PPL as partial replacement of sand by 30%......

Abstract: This paper presents a study of scenario of Construction Sustainability in India in terms of how the Indian construction companies are coping with the urge of incorporating sustainability in their projects. Since few decades there is a drastic increase in environmental degradation. Construction industries contributing to a major part of this cause. In order to prevent the degradation by construction companies we need to implement sustainable tools and practice of project management. In this study a brief check on the scenario of Indian construction companies has been taken in terms of their progress towards sustainable development. A questionnaire carrying questions related to sustainable practices in project management and the role of project management, was circulated among.....

Abstract: In the present paper, the effect of soil conditions on an irregular high-rise building seismic response has been studied in a comprehensive manner. Using a nonlinear time history analysis, the study was carried out using Etabs-2018 software. In order to examine this soil effect in the dynamic damage analysis, the irregular high-rise building was subjected to different seismic signals. Those signals were matched with response spectrum using the time domain method. The objective of this research is to study whether soil-structure interaction (SSI) affects the seismic performance and the vulnerability of reinforced concrete shear-walls building and consequently to assess if there in any modification.....

Abstract: Kertosari dam was built to irrigate an irrigation area of 2,056 Ha with a length of 14,659 Km of Kertosari irrigation canal. As a result of the non-optimal function of the sand trap to capture sediment, sedimentation occurs in the irrigation canal so that the carrying capacity of irrigation water discharge is reduced, eventually decreasing agricultural production in the long term which will hamper the self-sufficiency program launched by the government. Based on the results of the calculation of the amount of sediment transport that occurs the Kertosari Dam is 8,312 tons/day or 3,160 m3/day. Furthermore.....
