I wanted to know the advantages and disadvantages of arches in architecture.

When are they "needed", and could you give some examples?

I would really appreciate that.



Arches were originally developed to span openings with masonry units such as bricks or stone blocks, and they are still widely used for this purpose.

As building technology developed, arches were also formed from concrete and assembled from cast or rolled steel components. Arches are still a method of choice for constructing long span structures from these modern materials.

Arches are not "needed" for wood construction which relies on columns and beams to span openings, and most residential structures in the US are wood framed.

Arches are generally used in houses for aesthetic effect because they appear graceful and elegant while providing a counterpoint to plainer, rectangular forms.

Entire books have been written on the topic of arches. For starters, you may want to look at Wikipedia
