What is a high-rise building with a convex roof?

The convex roof is a hemispherical dome, which is a European-style building. When Europeans first designed hemispherical domes, there was no meaningful pursuit. Architects are more concerned with how to build, especially how to support the space of large buildings. Hemispherical shell is a good structural form to solve long-span problems. The earliest famous dome building is the Pantheon in Roman times, which spans 43 meters, but it is only spherical inside and can't be seen outside. During the Renaissance, this dome technology became more mature, and architects began to be keen to add the dome to the center of the church. This form is both reasonable and beautiful. After the tradition formed, churches, courts, parliaments and other important buildings began to inherit this tradition and gradually became the symbol of important buildings, so this form was adopted, including the White House. The development of modern science and technology has more structural forms to choose from, and a democratic society does not emphasize egoism. Therefore, the preference for domes is not so strong.
