#construction #civilengineering #earthquakeengineering The basic form of traditional Japanese architecture is a wooden foundation or pillar resting on a “foundation stone”. The Japanese style of “Ishibatate” or “standing on the stones” traditional framing has been perfected over 2000 years of trial and error. It is a framing style that aims to create a building that is so in tune with nature that it rests in it rather than being a prominent figure apart from it. The surface of the stone used as the foundation is uneven. The processing technique to precisely fit the wood into this uneven stone is called “Hikari-tsuke”. This style does not attempt to withstand an earthquake, rather using wood’s greatest strength, flexibility, the building implores several major strategies to absorb and disperse an earthquake’s energy. A foundation of columns on stone not fastened to the ground by any means. This strategy allows the building to shift as one in an earthquake’s tremors. a raised sub-structure called stiffeners instead of a sill foundation laid flat on stone or concrete.

Today is #SkyscraperDay. This term began to be used to describe tall buildings in the 19th century AD for any building over 10 stories (about 108 1/4 feet or 33 meters). "These marvelous buildings were first created in 1885 and have become a symbol of the modern industrial age" [source: https://lnkd.in/g5hptJaV ]. Humans have been constructing buildings over 10 stories for millennia, however. The Great Pyramid at Giza, one of the seven wonders of the ancient world and the only one still standing, stood at about 44 1/2 stories (482 feet/147 meters). It was the tallest manmade structure in the world for thousands of years.

Roman concrete, also known as opus caementicium, stands as a testament to the engineering prowess of ancient Rome. This remarkable building material played a crucial role in the construction of some of the most enduring structures of the Roman Empire, many of which still stand today. The secret to the longevity and strength of Roman concrete lies in its unique composition and innovative construction techniques. One of the key ingredients in Roman concrete was a volcanic ash called pozzolana, sourced primarily from the region around Mount Vesuvius. When mixed with lime and water, pozzolana created a chemical reaction that produced a durable and water-resistant binder. This binder, combined with aggregates such as rubble, stones, and bricks, formed a strong composite material that could withstand the test of time. The Romans also incorporated other additives into their concrete mixtures to enhance its properties. One such additive was seawater, which reacted with the lime to form additional minerals that reinforced the concrete and made it more resistant to erosion. This innovation allowed the Romans to build structures such as harbors, bridges, and aqueducts that could withstand the corrosive effects of seawater. The use of Roman concrete revolutionized construction techniques in the ancient world. Its exceptional durability and strength enabled the Romans to build massive structures that have endured for centuries. The Pantheon in Rome, with its iconic dome made of Roman concrete, is a prime example of the lasting legacy of this remarkable building material. In addition to its structural properties, Roman concrete also had aesthetic appeal. The Romans were able to mold and shape the concrete into intricate designs and patterns, allowing for the creation of visually stunning architectural masterpieces. The use of concrete in Roman architecture paved the way for the development of new building styles and techniques that would influence construction practices for centuries to come. Despite the advances made in modern concrete technology, Roman concrete continues to fascinate engineers and historians alike. Its longevity and resilience serve as a reminder of the ingenuity and skill of the ancient Romans. By studying the composition and construction techniques of Roman concrete, we can gain valuable insights into sustainable building practices and materials that may inform future innovations in the field of construction. Roman concrete stands as a remarkable achievement of ancient engineering and architecture. Its durability, strength, and versatility have left an indelible mark on the built environment of the Roman Empire and continue to inspire admiration and study to this day. #civilengineering #construction #engineering #creative

🏛️ Exploring Ancient Reinforced Concrete Techniques in the Pantheon 🏗️ 🌍 The Pantheon in Rome stands as a testament to the ingenuity of ancient engineering. Dating back to 126 AD, this iconic structure utilized innovative construction methods that resemble the principles of reinforced concrete, albeit without modern materials. 📐With an internal diameter of 43.4 meters (142.3 feet), almost half the length of a football field, it is the largest dome ever built without single piece of steel in concrete. ⚽️ 🛠️ Materials Innovation: The dome of the Pantheon was crafted from a concrete mix incorporating pozzolana, a volcanic ash found locally, and lime. This mixture, while lacking steel reinforcement, demonstrated incredible strength and durability. 🏗️ Design Strategies: The construction of the dome integrated a gradation of materials, employing a lighter concrete mix at the top and progressively denser compositions lower down. This strategic use of varying densities helped distribute the weight of the dome effectively. 🧱 Reinforcement Techniques: Ingenious design included horizontal brick rings within the structure, acting as reinforcement elements. These rings provided crucial support, minimizing stress and enhancing the dome's stability. 🗝️ Innovative Hollow Spaces: The dome's construction incorporated hollow spaces and cavities, a remarkable feature reducing overall weight without compromising structural integrity—a true testament to ancient architects' foresight. 🌟 The Pantheon's construction methods, blending materials, thoughtful design, and strategic reinforcement, highlight ancient engineering brilliance in achieving durable structures without modern-day steel reinforcement techniques. 🏛️ Let's celebrate these ancient marvels that continue to inspire modern construction practices!

Shaq Khang 👉 Centuries-old building technique uses poplar and willow twigs and plaster made of natural ingredients 👉 Traditional houses are weather, earthquake resistant, which is important in seismically active region. “This architecture is our asset, these Shaq Khang homes are our recognition,” Arif said. “And it is a fact that this architecture is disappearing from the region as people are making modern houses. “The twigs of poplars and willows are intricately woven together to form the walls of Shaq, creating a strong and interconnected structure,” he told Arab News. “To enhance its strength, we apply a plaster of mud mixed with various substances. For example, we add husk to make the mud more compact, and we even incorporate apricot juice to strengthen it like cement.” https://lnkd.in/ddhddtBK #sustainable #green #climatechange

How did the Romans build bridges? Roman bridges were remarkable feats of engineering, built using a combination of stone, concrete, and wooden scaffolding. The key to their durability was the use of arches, which efficiently distributed weight and allowed the bridges to span wide gaps. Construction began with temporary wooden frameworks called centering, which supported the arch stones until the keystone, the central stone, was placed, locking the arch in place. Romans used stone, particularly durable materials like limestone and volcanic rock, along with Roman concrete, a strong mixture of lime, water, and pozzolana (volcanic ash). The bridge foundations were carefully laid, often with cofferdams to divert water and create a dry working space. Once the arches were complete, the wooden scaffolding was removed, and the structure could support its own weight. This arch-based design, combined with precise construction techniques, allowed Roman bridges to withstand centuries of use and remain standing today, so that we still can use these bridges. And even today we have much to learn from these techniques, some of which are still in use today. ❓ Have you ever crossed a Roman bridge? #engineering #structuralengineering #structure #bridge For more: 📌 Follow #ImpressiveEngineering 📌 Click on the 🔔 and select “All”
