Bixby Creek Bridge
Bixby Creek Bridge, also known as Bixby Canyon Bridge, on the Big Sur coast of California, is one of the most photographed bridges in California due to its aesthetic design, "graceful architecture and magnificent setting". It is a reinforced concrete open-spandrel arch bridge. The bridge is south of San Francisco and south of Carmel in Monterey County on State Route 1. Before the opening of the bridge in 1932, residents of the Big Sur area were virtually cut off during winter due to blockages on the often impassable Old Coast Road, which led inland. The bridge was built under budget for $199,861 (equivalent to $ in dollars) and, at , was the longest concrete arch span in the California State Highway System. When it was completed, it was the highest single-span arch bridge in the world, and it remains one of the tallest. The land north and south of the bridge was privately owned until 1988 and 2001. A logging company obtained approval to harvest redwood on the former Bixby ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Buttress
A buttress is an architectural structure built against or projecting from a wall which serves to support or reinforce the wall. Buttresses are fairly common on more ancient buildings, as a means of providing support to act against the lateral (sideways) forces arising out of inadequately braced roof structures. The term ''counterfort'' can be synonymous with buttress and is often used when referring to dams, retaining walls and other structures holding back earth. Early examples of buttresses are found on the Eanna Temple (ancient Uruk), dating to as early as the 4th millennium BC. Terminology In addition to flying and ordinary buttresses, brick and masonry buttresses that support wall corners can be classified according to their ground plan. A clasping or clamped buttress has an L shaped ground plan surrounding the corner, an angled buttress has two buttresses meeting at the corner, a setback buttress is similar to an angled buttress but the buttresses are set back from t ...

Prestressed Concrete
Prestressed concrete is a form of concrete used in construction. It is substantially "prestressed" ( compressed) during production, in a manner that strengthens it against tensile forces which will exist when in service. Post-tensioned concreted is "structural concrete in which internal stresses have been introduced to reduce potential tensile stresses in the concrete resulting from loads." This compression is produced by the tensioning of high-strength "tendons" located within or adjacent to the concrete and is done to improve the performance of the concrete in service. Tendons may consist of single wires, multi-wire strands or threaded bars that are most commonly made from high-tensile steels, carbon fiber or aramid fiber. The essence of prestressed concrete is that once the initial compression has been applied, the resulting material has the characteristics of high-strength concrete when subject to any subsequent compression forces and of ductile high-strength steel when sub ...

Seismic Retrofit
Seismic retrofitting is the modification of existing structures to make them more resistant to seismic activity, ground motion, or soil failure due to earthquakes. With better understanding of seismic demand on structures and with our recent experiences with large earthquakes near urban centers, the need of seismic retrofitting is well acknowledged. Prior to the introduction of modern seismic codes in the late 1960s for developed countries (US, Japan etc.) and late 1970s for many other parts of the world (Turkey, China etc.), many structures were designed without adequate detailing and reinforcement for seismic protection. In view of the imminent problem, various research work has been carried out. State-of-the-art technical guidelines for seismic assessment, retrofit and rehabilitation have been published around the world – such as the ASCE-SEI 41 ...

San Andreas, California
San Andreas (Spanish for "St. Andrew") is an unincorporated census-designated place and the county seat of Calaveras County, California. The population was 2,783 at the 2010 census, up from 2,615 at the 2000 census. Like most towns in the region, it was founded during the California Gold Rush. The town is located on State Route 49 and is registered as California Historical Landmark #252. History Settled by Mexican gold miners in 1848 and named after the Catholic parish St. Andrew, the town has been a noted mining camp since early days. The gold from the initially discovered placers gave out after a few years, but the discovery of gold in an underground river channel in 1853 revitalized the camp and it soon became a town. Mining of the channels was lucrative enough for the town to completely rebuild after fires in 1858 and 1863. The gold discovered here contributed greatly to the success of the Union during the Civil War. In 1866, San Andreas became the seat of Calaveras Coun ...

Santa Cruz, California
Santa Cruz ( Spanish for "Holy Cross") is the county seat and largest city of Santa Cruz County, in Northern California. As of the 2020 census, the city population was 62,956. Situated on the northern edge of Monterey Bay, Santa Cruz is a popular tourist destination, owing to its beaches, surf culture, and historic landmarks. Santa Cruz was founded by the Spanish in 1791, when Fermín de Lasuén established Mission Santa Cruz. Soon after, a settlement grew up near the mission called Branciforte, which came to be known across Alta California for its lawlessness. With the Mexican secularization of the Californian missions in 1833, the former mission was divided and granted as rancho grants. Following the American Conquest of California, Santa Cruz eventually incorporated as a city in 1866. The creation of the Santa Cruz Beach Boardwalk in 1907 solidified the city's status as a seaside resort community, while the establishment of the University of California, Santa Cruz in ...

Falsework
Falsework consists of temporary structures used in construction to support a permanent structure until its construction is sufficiently advanced to support itself. For arches, this is specifically called centering. Falsework includes temporary support structures for formwork used to mold concreteHardie G.M. (1995) Building Construction: Principles, Practices, and Materials. New Jersey: Prentice Hall. (Pg 116, paragraph 1) in the construction of buildings, bridges, and elevated roadways. The British Standards of practice for falsework, BS 5975:2008, defines falsework as "Any temporary structure used to support a permanent structure while it is not self-supporting." History Falsework has been employed in bridge and viaduct construction since ancient times. The Romans were renowned for its use, as at the Limyra Bridge in Turkey. Until the turn of the 20th century almost all falsework was constructed from timber. To compensate for timber shortages in different regions and to ra ...

Great Depression
The Great Depression (19291939) was an economic shock that impacted most countries across the world. It was a period of economic depression that became evident after a major fall in stock prices in the United States. The Financial contagion, economic contagion began around September and led to the Wall Street Crash of 1929, Wall Street stock market crash of October 24 (Black Thursday). It was the longest, deepest, and most widespread depression of the 20th century. Between 1929 and 1932, worldwide Gross domestic product, gross domestic product (GDP) fell by an estimated 15%. By comparison, worldwide GDP fell by less than 1% from 2008 to 2009 during the Great Recession. Some economies started to recover by the mid-1930s. However, in many countries, the negative effects of the Great Depression lasted until the beginning of World War II. Devastating effects were seen in both rich and poor countries with falling personal income, prices, tax revenues, and profits. International t ...
