An Innovative Method for Wind Load Estimation in High-Rise Buildings Based on Data-Driven and AI Approaches

High-rise buildings are increasingly being constructed in urban areas worldwide, making accurate wind load estimation critical for structural safety and occupant comfort. Traditional wind load estimation relies on empirical formulas, wind tunnel testing, and computational fluid dynamics (CFD). However, these methods often require significant computational resources, time, and financial investment. Moreover, real-world wind conditions are complex, exhibiting nonlinear and stochastic behavior that conventional models struggle to capture. In response to these challenges, integrating data-driven methodologies and artificial intelligence (AI) into wind load estimation offers a promising solution. The estimation of wind loads on high-rise buildings is a critical aspect of structural engineering, particularly as urban environments evolve and the heights of buildings increase. Recent advancements in data-driven and artificial intelligence (AI) techniques have provided innovative methodologies for improving the accuracy and efficiency of wind load estimations. This synthesis explores various approaches that leverage computational fluid dynamics (CFD), machine learning, and hybrid models to enhance wind load predictions.

Understanding Damping in Tall Buildings: A Data-Driven Approach

Tall buildings are engineering marvels designed to withstand environmental forces such as wind and seismic activities. Among the key factors influencing their structural integrity is damping, a phenomenon that governs how a building dissipates energy from vibrations. Unlike mass and stiffness, damping is difficult to estimate due to the complex interplay of materials, frictional effects, and structural interactions. This article explores how a data-driven, probabilistic approach improves the understanding and prediction of damping behavior in high-rise structures.

Aeroelastic Energy Harvesting: A Game-Changer for Indonesia’s Renewable Energy Future

Indonesia, with its extensive coastline and archipelagic geography, holds significant potential for wind energy development. The country's wind energy potential is estimated at around 9.3 GW, primarily concentrated in regions like South Sulawesi, East Nusa Tenggara, and West Java. Coastal areas and highlands with average wind speeds between 4 to 6 m/s offer viable sites for small to medium-scale wind turbines. Notable projects like the Sidrap Wind Farm in South Sulawesi and the Tolo Wind Farm in Jeneponto highlight the possibility of harnessing this renewable resource. Together, these farms contribute approximately 150 MW of installed capacity, underscoring the early but promising stages of wind energy adoption in Indonesia. Despite the potential, Indonesia faces several challenges in expanding its wind energy sector. The moderate wind speeds in many areas limit the feasibility of large-scale wind farms, and high transmission costs arise from the remote locations of the best wind resources. Infrastructure limitations, particularly in rural and off-grid areas, complicate the integration of wind energy into the national grid. Additionally, complex land-use regulations and public resistance due to a lack of awareness about wind energy benefits create further obstacles. The financial environment for renewable energy projects also needs improvement, as investors often face regulatory uncertainties and limited incentives.
