It also softens the force of seismic activities by sending vibrations back down the structure. This technique allows the distribution of force that keeps structures to keep standing despite seismic activities. In cross bracing, two diagonal supports are placed in a way that they form the letter X. Cross bracing is the process of intersecting diagonal support to make building structures stronger. At the same time, this system functions as a shock absorber – a technology that should also be considered in developing earthquake-resistant structures.ģ. With a system of ball bearings and padded cylinders, skyscrapers can stand on their own. This feature is illustrated in skyscrapers. During earthquakes, structures should have a good shock absorber. Needless to say, a good foundation can go a long way.Īvoid building on loose or soft ground to maintain a structure that limits excessive stress and movement. Buildings become hazards during earthquakes due to their tendency to crumble after a few massive tremors. Earthquakes are caused by the movements of the plates beneath the Earth’s surface. This prevents placing too much pressure on just one area of the structure, which helps keep the building together in an earthquake.Ģ. Lateral stiffness allows structures to move side to side equally during an earthquake. Building a vertically stiff structure is easy, but for earthquake-proofing, lateral stiffness is important. Here are features that earthquake-resistant structures have.ġ. Most modern structures are earthquake resistant as they are built with earthquake-proofing that can resist even intensity 8 earthquakes, the highest on the Richter scale. Features that Make a Structure Earthquake Resistant We can avoid these problems by making our structures earthquake-proof. More than the damage to properties, we need to prevent the loss of lives. Still, we have to ensure that our homes and properties are safe in case of earthquakes. Fortunately, most of them are non-destructive. What we have to prepare for are earthquakes, as PHIVOLCS, the country’s earthquake authority reports 100 to 150 earthquake occurrences per year. There are more than 20 active volcanoes in the country, but if you live nowhere near them, then you really don’t have to worry about experiencing volcanic eruptions. Being in the Pacific Ring of Fire, the Philippines is prone to experiencing frequent earthquakes and volcanic eruptions.
