Bangladesh frequently faces devastating tropical cyclones due to its geographical location. The Bangladesh National Building Code (BNBC) 2020 introduces specific wind exposure provisions to ensure structural safety and resilience against high winds. These provisions define critical design parameters, including wind speeds, topographic factors, and importance levels, based on geographical conditions. This study investigates the impact of BNBC 2020 wind exposure provisions on the construction costs of high-rise buildings. Using ETABS 2016, three 15-story dual-system RCC buildings were analyzed under varying wind exposure categories, with uniform earthquake provisions. Results revealed significant cost variations, with material requirements increasing by up to 22% in higher wind exposure categories. This research contributes valuable insights into the relationship between wind exposure provisions and construction costs, aiding stakeholders in optimizing structural designs and budgets for cyclone-prone regions like Bangladesh.

The sugar industry plays a vital role in India\'s agro-based economy by contributing to agricultural development, rural employment, industrial growth, and renewable energy production. However, several public-sector sugar factories have experienced persistent operational and financial challenges due to declining recovery rates, increasing production costs, inefficient utilization of installed capacity, and volatile sugar prices. This study evaluates the economic performance and profitability of Mysore Sugar Company Ltd. (MYSUGAR), Mandya, Karnataka, using secondary data collected from factory records for the period 2009–10 to 2018–19. The analysis focuses on sugar production, by-product generation, sugar losses, production costs, and profitability. The results indicate substantial fluctuations in sugarcane crushing and sugar production throughout the study period. The average sugar recovery rate was only 6.79%, significantly lower than the national average, indicating operational inefficiencies and poor cane quality. Bagasse, molasses, and press mud were produced consistently, with average yields of 29.00%, 5.96%, and 3.13%, respectively, highlighting considerable potential for value addition. Despite this, the factory experienced increasing production costs, primarily driven by rising sugarcane procurement prices and underutilization of installed processing capacity. The study provides valuable insights for policymakers, sugar factory managers, and researchers seeking strategies to improve the sustainability and competitiveness of public-sector sugar industries in India.
