Evaluation of Lateral Load Resisting Systems in High-Rise Buildings

/in /by

The rapid urbanization and the scarcity of residential space in metropolitan areas necessitate the construction of tall structures to meet the growing accommodation demands. This research paper focuses mainly on the structural act of high-rise structures under lateral loads, especially earthquake forces. Three lateral load resisting systems, namely outrigger system, shear wall at core and shear wall at corner are compared and analysed. The study reviews relevant literature, discussing parameters affecting the fundamental time period of structural models and the effectiveness of distributed belt wall systems. The research methodology involves the analysis of a 40-storey regular office building using three different lateral load resisting systems. The results obtained through response spectrum analysis, shows that the outrigger system exhibits efficient structural capability in tall buildings. The maximum lateral displacement is significantly reduced in the outrigger system compared to core shear-wall and corner-shear wall. The study concludes that enhancing lateral load resistance and providing a transition path to perimeter columns subjected to lateral load, as seen in the outrigger-system, proves effective in mitigating the impact of earthquake loads on high-rise buildings.

Relevance of IPR in Small Businesses

/in /by

Small businesses in India have always been one of the major occupations in rural as well as urban terrain and they are major source of income for the middle class group. As urbanization has increased the demand for the small services like grocery shops, bakeries, vegetable shops, laundry shops, juice centers, sweet shops, small hotels etc. Majorly the urban population is a mix of all the classes of people but a considerable portion is occupied by the middle and low income group, which has resulted in requirement of small services, and retail shops. As of a result of which the small businesses mushroom in the different localities, in different sizes so that they can cater to all the segments of consumers. Small business organizations contribute to the economy significantly by distributing the finished goods to the ultimate consumers, and they also create jobs in smaller units. The large business organizations contribute to economy by creating jobs in a bulk, economies of scale. The large scale organizations have the accessibility to hire legal professionals like legal advisers and naturally they give the suggestions on legal aspects for a smooth conduct of the business. In this context large or medium sized organizations have proximity to legal protection for their inventions, design, copyrights, trademarks etc, and they consciously protect their rights by patents or trademark and so on. In this article we have made an attempt to understand the extent of application of IPR in small and micro businesses.

Brazil’s Economic Potential with Carbon Credits: A Study of the “Mata Do Buraquinho” – Brazil

/in /by

Introduction: Public (state) concern about the climate has, in turn, catalyzed the creation between global governments and transnational companies, and these models are subject to risk-consequence type measures, the conduct of which is now known as the voluntary carbon credit market. The article in question deals with one of the most talked-about economic instruments for combating global warming in international politics, the carbon credit market.

Objective: The article in question proposes a reflection on this subject, which has been so much talked about in recent years, focusing on its economic perspective and using a case study methodology to support its results.

Theoretical framework: The mitigation of greenhouse gas (GHG) emissions is a necessary condition to lead to a low-carbon economy, and the best way to achieve this is through the application of economic instruments. Such as putting a price on carbon, making this transition quicker and less costly from a social point of view. In this way, with a higher relative price for pollution, private agents will choose between paying for or reducing pollution, comparing the marginal cost of control with the price of carbon.

Methodology: Initially, a bibliographical review was made of the economic theoretical framework that underpins one of the instruments considered most efficient in combating climate change, the carbon credit market. In another part of this work, a practical application of this mechanism was carried out, using an evaluation methodology for an application of this instrument in the municipality of João Pessoa -PB, which stands out for being one of the most wooded cities in Brazil and for having some conservation units in its territory, such as the one used in the work, the Mata do Buraquinho Wildlife Reserve.

Results: The sale of the ecosystem services that the forest offers, in this case its capacity to absorb CO2, could improve the conditions for maintaining the area and perhaps attract more people to visit it. Thus, the value found for “Mata do Buraquinho” was R$61,968.26.

Effects of Deforestation and Anthropogenic Aspects on Streamflow in the Mau Forest Catchments in Kenya: Hydrological Modelling of Surface Water Yields from Sondu River Basin

/in /by

Climatic factors determine the amount and distribution of atmospheric water received at the land surface while the land cover conditions determine the partitioning of this water into different hydrological components and ultimately the catchment surface water yields. This study assessed the effects of deforestation of a tropical catchment on surface water yields to address fluctuating flows of the rivers emanating from Mau Forest, the largest water tower in Kenya. Sondu basin traverses Southwest Mau Forest covering an area of 3500 km2. The main channel in the basin flows in a southwest direction into Lake Victoria in an altitudinal range of 2900 to 1130 m a.s.l over a length of 173 km. Different deforestation scenarios over the basin were integrated with climate data to form inputs to a hydrologic model, Soil and Water Assessment Tool (SWAT). Using model outputs, the effects of deforestation on annual and seasonal surface water yields, represented by changes in streamflow volumes under different deforestation scenarios, were evaluated. Deforestation scenarios were derived from a supervised classification scheme of time series of LANDSAT images (1970-2020) to show deforestation trends. Effects of deforestation on the catchment water-yielding capacity were estimated as the ratio of the difference between simulated yields under different deforestation scenarios and those simulated under the pre-deforestation scenario of the 1970s decade. Results show that forest cover declined by 21% and a corresponding growth in land under agriculture by 26% in the period 1970-2020.  The decline in forest coverage resulted in an increase in the annual surface water yields of about 23% (from 152 to 187 MCM/year) throughout the period of study. This implies that there is less recharge of groundwater due to decreased infiltration and subsequent storage leading to lower flows during the dry seasons and increased flood frequencies in the basin during the wet seasons. The study has therefore, demonstrated that deforestation has reduced the stability of Mau Forest as a water tower and conservation of the forest will enhance its water-holding capacity thereby ensuring a stable water supply to rivers emanating from it as a way of combating floods and low flows in the basin. The resultant impacts on environment and society are displacements from floods and destruction of properties.
