In the wake of devastating earthquakes in Lombok and Palu in 2018, a critical analysis of reinforced concrete construction has emerged, shedding light on the vulnerabilities that led to widespread damage and collapse. The research, conducted by Jafril Tanjung from Universitas Andalas, identifies key factors that contributed to the structural failures observed in the aftermath of these natural disasters.
The study highlights that the quality of concrete used in construction plays a pivotal role in a building’s ability to withstand seismic forces. “Low-quality concrete, which may arise from improper mixing or inadequate strength, can render a structure brittle,” Tanjung explains. This brittleness significantly increases the likelihood of collapse during an earthquake, a risk that is exacerbated by non-standard reinforcement detailing practices.
Tanjung’s observations revealed that many buildings suffered from insufficient reinforcement, particularly at critical points such as beam and column connections. “The lack of shear reinforcement in structural connections compromises the strength and stiffness of the entire system,” he notes. This insight underscores the importance of adhering to established construction standards, which are often overlooked in the rush to complete projects.
Additionally, the research delves into the role of brick walls in reinforced concrete structures. The improper installation and placement of these walls can further jeopardize a building’s integrity during seismic events. By ensuring that both concrete quality and reinforcement detailing meet stringent standards, the construction sector can significantly enhance the resilience of structures against earthquakes.
The implications of this research extend beyond academic interest; they resonate deeply within the commercial landscape of the construction industry. With the threat of natural disasters looming, developers and contractors are increasingly aware of the need for robust building practices. Investing in high-quality materials and adhering to proper construction protocols not only safeguards lives but also protects financial investments in real estate.
As the construction industry grapples with the lessons learned from past disasters, Tanjung’s findings serve as a clarion call for change. “Proper implementation of structural design specifications and vigilant monitoring during construction can dramatically reduce the risk of damage caused by earthquakes,” he asserts. This research, published in ‘Jurnal Bangunan, Konstruksi & Desain’ (Journal of Buildings, Construction & Design), is poised to influence future developments in construction practices, emphasizing the necessity of quality and compliance in creating resilient infrastructures.
As the sector moves forward, the integration of these insights into everyday building practices may not only enhance safety but also foster a culture of accountability and excellence in construction, ultimately shaping a more resilient future.
