Earthquake Resistant Building Research Paper

[Rachelle Shriver]

Everycountry has hundreds of rules and regulations surrounding the construction of buildings. In countries such as Chile and Japan, which face regular earthquakes, many extra rules have been put in place to ensure buildings can withstand these disasters as well as possible.

Designers can remedy this by adding a flexible steel skeleton made of something called rebar, which is also known as reinforcement steel. Casting rebar inside concrete boosts the overall strength of the concrete and enhances its ability to withstand force.

After the Kobe earthquake in 1995, which killed more than 6,000 people, Japan carried out extensive research into making buildings earthquake-resistant, including retrofitting older structures, the New York Times reported. Like Chile, it put in place strict rules around making sure buildings are able to withstand earthquakes.

It says making sure buildings can withstand earthquakes not only saves lives and prevents injuries, but reduces the economic consequences of these disasters. There are also environmental benefits, as there is less need for debris to go to landfill, and no consumption and emissions spent on reconstruction efforts.

Our study aims to set standards and designs for earthquake-resistant buildings and to emphasize the technical and engineering requirements for including earthquake-resistant buildings when designing and implementing homes and residential buildings under current or future implementation for fear of Iraq entering an earthquake zone, as happened a few years ago in northern and southern Iraq, as the continued occurrence of tremors The ground in Iraq's neighboring and regional countries may contribute to destabilization in Iraq, and residents may be concerned about the possibility of their buildings being exposed to violent tremors. For fear that Iraq may enter the seismic zone, we find that it is the responsibility of scientists and researchers in this field to contribute effectively to finding design methods for earthquake-resistant buildings, as this is a very important task of setting mandatory structural design standards for all buildings rented to public and private engineering departments and offices, and ensuring their flexibility and immunity. In the face of dangerous earthquakes, it must be taken into consideration in the public, private and mixed sectors.

Earthquake-resistant buildings are designed to ensure that the building resists earthquakes and is supported by strength, rigidity, support, and inelastic deformation capacity that is large enough to withstand a certain level of earthquake-generating force. This is generally achieved by selecting the appropriate structural configuration and careful detailing of structural members, such as beams and columns, the connections between them and angles. The most advanced earthquake resistance technologies aim not only to strengthen the building, but also to reduce the earthquake-generating forces affecting it. The extensive research spanning civil engineering, geological engineering, and mechanical engineering signifies an innovative and interdisciplinary approach to addressing the critical issue of earthquake resilience in construction. The integration of your seismic technology, based on compression and anchoring mechanisms, demonstrates substantial promise in enhancing structural strength and stability when confronted with seismic forces. Your meticulous analysis of simulation outcomes, which methodically identifies variances in placement and anchoring, underscores the paramount importance of precision and methodological rigor in research and analysis. Your methodology's capacity to mitigate deformation, eliminate forces and torques, and increase the effective cross-sectional area of walls presents a highly encouraging avenue for seismic retrofitting and construction practices. Moreover, your emphasis on the discord between steel tensile strength and concrete shear strength underscores the often-overlooked intricacies of material behavior during seismic events. Your steadfast commitment to addressing these intricacies is commendable, as it holds the potential to significantly shape the development of cost-efficient and resilient earthquake-resistant building methodologies. While the financial and recognition challenges you encounter are undeniably formidable, your unwavering dedication to this pivotal research underscores the potential to revolutionize the field, ultimately fostering safer urban environments in the face of seismic hazards.

Finding the optimal balance between elasticity, ductility, dynamics, and cost-efficiency remains an ongoing challenge. While elastic columns and rigid walls each have their advantages and drawbacks, a potential solution in the form of elongated walls with prestressed and soil-consolidated ends emerges as a promising yet underutilized approach. These elongated walls offer the potential to enhance seismic resilience by redirecting seismic forces away from the structure, minimizing mass-induced inertia, and thereby reducing the seismic loads imposed on the building. This innovative concept holds the promise of not only bolstering structural performance but also addressing cost concerns by substantially reducing the need for reinforcement materials, potentially revolutionizing seismic design practices in the construction industry.

In January 1994 I entered the University of Moratuwa, in the suburbs of Colombo, Sri Lanka, to study engineering. There was a programme in which academics from different departments introduced their disciplines to the new undergraduates, so that the latter could think about their choice of specialisation in the beginning of the second year.

In the second year, I selected Civil Engineering as my specialisation, beginning an affair that goes on even today even though my focus has shifted to sustainability education, communication and engagement.

Our batch of 100, divided into 12 groups, took part in the 10-day residential survey camp held in Guruthalawa in hill country in central Sri Lanka in August 1997. Each group, carrying out six days of field work, was to propose a dam axis to construct a reservoir in a basin. However, it was on the final night that the camp really climaxed (after all official work was over), with Survey Nite of music, dancing and fun.

I worked on this project along with Aravinda, another batch mate, who created a set of models for use in lectures. I wrote a book of nearly 100 pages, Structures EXPOSED, No Maths OF COURSE! and the artist in me took care of the diagrams and sketches, which formed the core of the book in the absence of mathematics.

After the short research project on structural behaviour, I started reading for an MPhil on passive techniques for energy efficiency in buildings in tropical climates, taking Sri Lanka as the case. Its main supervisor was Professor Thishan Jayasinghe and Professor Rahula Attalage from the Department of Mechanical Engineering was co-supervisor.

After postgraduate studies, I worked as a Communications Consultant/ Editor for Holcim (Lanka) Ltd, which was part of the global cement and concrete supplier Holcim Group (now LafargeHolcim). This full-time role gave me an opportunity to gain access to professionals in the areas of cement, concrete and construction. Thus, my Knowledge Journalism endeavour, which had been until then limited to the academia, expanded to the industry too.

Still, I thought that it was far too more serious to engage the general public with civil engineering. The result was an approach of light-hearted journalism, taking aspects of civil engineering to the public domain in an engaging fashion, usually based on the lecture notes of academics.

In recognition of my role in promoting structural engineering in the national press, the Society of Structural Engineers Sri Lanka (SSE-SL) twice awarded me with special honoraria, in 1997 and in 2000.

I was born an artist and then civil engineering was the first step of my tertiary education, which subsequently stretched to sciences and social sciences in the terrain of sustainability. This multidisciplinary combination has given me a wider perspective that is essential for advancing sustainability education.

After a large earthquake, the news inundates us with images of crumbled concrete, twisted steel, and disaster recovery teams searching through rubble for survivors. According to the California Department of Conservation, the 1989 Loma Prieta earthquake caused 63 deaths, and 3,757 people reported injuries from the disaster. The World Health Organization says that earthquakes caused nearly 750,000 deaths worldwide between 1998 and 2017. And more than 125 million people were affected, either through injuries or displacement.
