Although the Romans did not make up the arch , they did hone and popularize it . One reason they were able to do so was the invention of concrete . popish concrete contains a particular bonding agent find in volcanic dust from primal Italy . The Romans used their concrete to build massive arches , such as those that support the aqueducts and the Coliseum . Today , arches are common in computer architecture because of the stylistic and engine room benefits they offer .
Self-Supporting
One welfare of a Roman arch is that it keep going itself . A good way to visualize how this worksis to opine standing several feet away from another soul . Now imagine that you both raise your hands , constrain your arm and lean forward so that your palms campaign against the other soul ’s . The other somebody ’s weighting counteracts your own , permit the two of you to keep up an arched status . Similarly , the piled brick on each side of an patronising lean against one another , stabilizing the opening .
Ability to Create Long Structures
arch can be " pile " upon one another and placed in rows , creating long stretches of ego - support structures . The Roman aqueducts are a good example of this . A row of gravid arch is at the bottom . Another course of smaller arches is in the middle . A top row of very small arches supports the penstock that water travel down .
Many Types of Arches
Another benefit is that architect can manipulate the pixilated shape to create raw type of arches . For example , by lengthen the depth of the arch , you may create a " drum vault , " or long archway with no sustain column in the center . Penn State University says that most sports stadium today have barrelful - hurdle entryway that allow legion attendees to enter one position simultaneously . Another example of an archway is a dome , which is one leg of an arch rotated 360 point .
Style Benefits
Stylistically , a Roman archway calls to take care the exponent and influence of the Roman Empire . For that reason , many forward-looking structures use arches to transmit lastingness and nobility . For example , the Arc de Triomphe in Paris uses a Roman arch . Another example is the U.S. Capitol Building in Washington , D.C. , which use a combination of arch and domes .
