点评:Creative aspects of the design of the Pantheon include:
* Concrete Innovation:
The Pantheon's dome is the largest unreinforced concrete dome ever built. The Romans developed high-quality concrete and used it to create the dome, arches, and vaults.
* Differential Concrete Mix:
The concrete mix wasn't uniform throughout the dome. Heavier materials like brick and tufa were used at the base, while lighter materials like pumice were incorporated above.
* The Oculus:
The oculus, a circular opening at the top of the dome, reduced the overall weight and provided a source of natural light. This also allowed for a unique lighting effect on certain days of the year, with the sun illuminating the interior in a dramatic way.
* Step-Rings: Step-rings were incorporated into the construction, which helped to distribute the weight of the dome and counteract hoop stress
Some prominent examples of buildings that are considered copies or are heavily influenced by the Pantheon's construction include:
* The Jefferson Memorial in Washington, D.C., designed by John Russell Pope, is a notable example, often considered a direct copy of the Pantheon's dome and portico.
* The University of Virginia Rotunda, designed by Thomas Jefferson, is a direct homage to the Pantheon and served as the university's library.
* The U.S. Capitol Building in Washington, D.C. incorporates a massive dome and a grand entrance influenced by the Pantheon's design.

* 混凝土创新:万神殿的穹顶是迄今为止建造的最大无钢筋混凝土穹顶。罗马人研发了高品质混凝土,并将其用于建造穹顶、拱券和拱顶结构。
* 差异化混凝土配比:穹顶各处的混凝土配比并不均匀。底部使用了砖块和凝灰岩等较重的材料,而上部则使用了浮石等较轻的材料。
* 天窗:穹顶顶部的圆形开口——天窗,减轻了整体重量,并引入了自然光。在一年中的某些日子里,阳光以戏剧性的方式照射在穹顶内部,营造出独特的光影效果。
* 阶梯环:阶梯环被融入到建筑结构中,有助于分散穹顶的重量并抵消环向应力。
一些被认为是仿照或深受万神殿建筑风格影响的著名建筑包括:
* 位于华盛顿特区的杰斐逊纪念堂,由约翰·罗素·波普设计,是一个显著的例子,通常被认为是直接仿照万神殿的穹顶和门廊。
* 弗吉尼亚大学圆形大厅,由托马斯·杰斐逊设计,是对万神殿的直接致敬,并曾作为该大学的图书馆。
* 位于华盛顿特区的美国国会大厦,其巨大的穹顶和宏伟的入口也受到了万神殿设计的影响。
