One very large shake table is at the Pacific Earthquake Engineering Research Center (PEER) at the Department of Civil and Environmental Engineering, University of California, Irvine. A shake table is a special type of table that engineers use to simulate an earthquake on model buildings. One way to test a design for stability to lateral forces is to use a shake table. Some of the world's tallest buildings, like the Petronas Towers, are an excellent example of this type of design because Malaysia is in an area that experiences frequent earthquake activity. If an engineer is going to design a building in earthquake country, then they need to be sure that their design can withstand lateral forces. Earthquakes occur when the earth's tectonic plates, which are slowly moving relative to each other, get stuck for a while and then suddenly come loose. One type of force that can weaken a structure is a lateral (side-to-side) shaking force, like that experienced during an earthquake. If the design is stable, then these forces will not weaken the structure or cause the structure to collapse. Forces come from many sources: gravity, people inside, weight of building materials, weather, and environmental impacts.

On the far right, we have the 7th tallest communications tower in the world, simply named the KL Tower which broadcasts free to air radio and TV channels.Edited by Ben Finio, PhD, Science Buddies In the middle we have the Petronas Towers, sometimes referred to as the Twin Towers of Malaysia, which was once the tallest buildings in the world from 1998 until 2004. If we step back in time, it was once the home to various key departments during the British administration. The left-most building, Sultan Abdul Samad Building was built in the 19th century and today houses the Information, Communications and Culture ministry. These are great, iconic buildings that highlight a spectacular, multicultural and multi-racial city. This build of three iconic buildings in Kuala Lumpur, the capital city of Malaysia expresses the love that Ng Wen Yeh has for his country. When LEGO released their new Skyline Architecture series, it was inevitable that we started seeing LEGO builders take the diminutive buildings to heart and begin creating skylines closer to their own homeland that LEGO missed in their official sets. This makes for an interesting mix of architecture and an extremely impressive LEGO model. The builder took on a daunting challenge recreating Hearst Tower, but the effort paid off with this accurate and realistically detailed model – which includes the original six-story base as well as the 40-story glass tower finished in 2006, here accomplished perfectly with triangular road sign elements. One building which exemplifies this mix of old and new is the Hearst Tower, painstakingly recreated here in LEGO form by Daniel Stoffler.īuilt for and named after the famous American publisher William Randolph Hearst, the building claims a spot as the headquarters for one of the world’s largest media corporations, Hearst Communications, with ownership of numerous newspapers and publications including Esquire, Harper’s Bazaar and Cosmopolitan. Past, present, and future often lie within the same block, Art Deco and Modern architecture mingling to reflect the city’s status as a permanent symbol of capitalism. Manhattan bustles with the edifices of American enterprise, towering symbols of capitalism whose many styles span New York City’s distinct historical periods.
