Multilobed Arches: A Series of Small Arcs at the Edges

An arch with a wavy edge. The inner edge of the arch is not a smooth curve, but is continuously composed of five to nine small semicircular arcs, like petals; each small arc is built of brick. This type of arch is typically used for smaller openings and cloisters, not large in size but high in density. Several adjacent arches share slender brick columns. Avoid: making the number of small arcs even; making the size of the small arcs inconsistent; using carved stone for the arcs; using multifoil arches for very large openings.

一道邊緣呈波浪的拱。拱的內緣不是一條光滑的弧,而是由五到九個小的半圓弧連續組成,像花瓣一樣;每一個小弧都由磚砌出。這種拱通常用在較小的開口與迴廊上,尺寸不大但密度高。相鄰的幾道拱共用細瘦的磚砌柱。避免:把小弧的數量做成偶數、讓小弧的大小不一致、使用石材雕出弧形、把多葉拱用在很大的開口上。
