What are the challenges in structural design for irregularly shaped buildings?

图片
The structural design of non-standard geometric buildings represents the most critical and challenging aspect of their realization. The difficulties extend far beyond merely “how to make it stand,” permeating the entire process from concept development and calculations through construction and use. Below are the primary challenges in the structural design of non-standard geometric buildings, presented in order from core to derivative issues: 1. Core Mechanical Challenge: Non-Standard Load Paths In traditional buildings (such as rectangular boxes), load transfer paths are clear and direct: floor slab → beam → column → foundation → ground. Forces are primarily transmitted vertically downward. In contrast, load paths in irregularly shaped structures are often highly complex and convoluted. Challenge: Forces do not obediently travel straight downward. They “detour” through curved surfaces, diagonal bracing, and irregular grids, generating massive torsional forces, bending moments, and hor...

Common connection methods for steel structures

Common connection methods for steel structures:



1. A steel structure is made up of a number of elements combined. The role of the connection is to combine the plates or sections into members in a certain way, or to combine several members into a whole structure in order to ensure that it works together. Therefore, the connection method and its quality directly affect the working performance of the steel structure.

2. At present, the steel structure is commonly connected by welding, bolting or riveting. The earliest common bolt connection was used from about the middle of the 18th century, and the rivet connection was introduced in the 1920s, while the weld connection appeared in the second half of the 19th century. Since the middle of the century, high-strength bolted connections have been developed.
