Comparative analysis of collapse loads of slabs supported on orthogonal Sided frames with beam/column joint fixed | Author : Osuji SO* and Adhekoyibo LO | Abstract | Full Text | Abstract :This research evaluates the collapse loads of slab supported on orthogonal sided frames with beam/ column joint fixed. Two frame models were investigated (one with moment of resistance of slab (MRS) > moment of resistance of beam (MRB) and the other with moment of resistance of slab (MRS) < moment of resistance of beam (MRB).
A reinforced concrete prototype of 3m×3m× 3m frame with a reduction factor of 3 was designed and constructed. A model of it constructed and cast with a micro concrete of 1:6 mix ratio. The models were allowed to cure for 28days before being loaded directly until collapse. Loading of the RC frame model was done by a fabricated loading box of 1.0 ×1.0×3.0m size place on top of its slab. Sands were poured into the panel using head pans. The weight of sand on each head pans (1.84KN). Two dial gauges were used; one was set at the center of the bottom of the slab while the other was set below the center of the bottom of the beam to monitor and measure the deflection at ten head pans of sand. |
| User Response – Based Sustainable Solutions to Traffic Congestion Problem using Public Transport: The Case of Uttara, Dhaka | Author : ATM Abir*, MD Mostafizur Rahman, Farjana Islam, Raisa Bashar and Sirajul Islam | Abstract | Full Text | Abstract :For a country of millions, traffic congestion significantly reduces the economic productivity. This statement holds true for most urban areas of the world, especially Dhaka, the mega-city of Bangladesh. An area of Dhaka which has a lot of potential in terms of both as a residential and commercial region, is undoubtedly the suburb of Uttara. Along with being adjacent to the airport on one side and having a link to industrial areas like Gazipur and Savar on the other, it also has residential amenities in its numerous blocks, making it a colony for traffic congestion. Unfortunately, no sustainable solution has come about to successfully reduce this problem. Hence, this paper tries to understand where the problems lie from the perspectives of the most important stakeholders – the residents and commuters of the area. It supports the use of their simple thinking to reach solutions through suasive instruments, like training and awareness-building campaigns, instead of spending millions on building lengths of roads and investing in technology. A survey of 150 bus passengers and 150 private car owners, coupled with literature review were conducted to accumulate, identify and address the traffic congestion reasons and associated issues. These problems were later used to propose recommendations. Responses revealed that the satisfaction levels of the commuters fell mostly under the ‘dissatisfied’ category (78%), based on parameters like fitness of the bus and driver, behavior of drivers and conductors, etc. Unsurprisingly, most respondents showed interest to pay an extra bit of fare for better bus service and believed that these would greatly help to mitigate the issue of running this sector with ‘unskilled’ and ‘unprofessional’ drivers/conductors (92%). Additionally, the large presence of private cars seemed to cause higher amounts of traffic congestion, but 56% of these users believed that the public buses had poor service and hence, their decision to avoid it as a regular commuting option. Hence, it was clear from the responses and their analysis that only a reliable, comfortable, and safe bus service system (including good drivers, conductors and buses themselves) is what will encourage more people to travel in public buses, leaving behind their private cars. This would in turn, greatly reduce the traffic congestion problem as people will be able/want to follow the traffic regulations better. |
| A Survey of Solid Waste Management in Chennai (A Case Study of Around Koyambedu Market and Madhavaram Poultry Farms) | Author : Visuvasam Motcha Rakkini* and Savariar Vincent | Abstract | Full Text | Abstract :The well managed successful waste management programme increases the health and environmental quality of the country. This survey examines the status of Solid Waste management at metropolitan city, Chennai, Tamil Nadu (Koyambedu market and Madhavaram poultry farms). This survey is helpful for the people to make awareness about waste management. A pretested and self-administered questionnaire was used for primary data collection covering 100 peoples which were selected randomly. Data were analyzed according to the descriptive statistics. Different organic wastes comprising plant and animal constituents such as vegetable waste- lady’s finger, Brinjal, Radish, Beans carrot, chow-chow, beetroot, clustered beans, snake gourd, tomatoes, egg shell, feather, skin etc. The results also showed that 58% of the households were not aware of waste recycling, reuse & reduction. |
| Should National Environmental Policy focus on developing more oil resources or developing renewable energy sources? | Author : Utpal Kumar Nandy, Shravani Nandy and Antara Nandy* | Abstract | Full Text | Abstract :United Arab Emirates (UAE) is a nation which is gifted with abundant reserves of oil and natural gas, thus occupying seventh position in the world. Because of its vast reserves, the oil sector plays a pivotal role in running the economic system of nation. Though the country has been making steady progress in other industries such as real estate, tourism, aviation etc. the oil industry holds the key role in its sustenance and development. However, at the same time the world is threatened by the rapidly depleting natural resources like coal and petroleum. While on the other hand their demand is on a sharp rise, due to the constantly growing population and their needs. The capital city of UAE, Abu Dhabi too is witnessing a steeply rising population level due to several factors like immigration of expatriates. With the growth in population, the pressure on the available resources is increasing exponentially. |
| Study on improvement of manpower performance & safety in construction firms | Author : Ananth Purushothaman* | Abstract | Full Text | Abstract :The construction an industry everywhere faces problems and challenges in the developing countries, this is study aim to improve the manpower of performance and safety of the construction firms. In this project work analyses the safety and manpower performance in the construction firms in additionally the lot of literatures review and build the questionnaires to conduct the survey in the field of constructor. When it is use collect data among the 25 workers to know the risk factors and statistical analysis to give some suggestion still had been reducing the fatigue of workers and increasing facilitate for the work hence develop as well as improve the performance of manpower and performing every construction work in a safe manner. |
