This encyclopedia provides an all-embracing selection of analytical floor periods. It presents concise definitions and outline for greater than 500 surfaces and categorizes them in 38 sessions of analytical surfaces. All periods are go references to the unique literature in an exceptional bibliography.

The encyclopedia is of specific curiosity to structural and civil engineers and serves as worthwhile reference for mathematicians.

**Discrete Optimization in Architecture: Building Envelope**

This ebook explores the super modular platforms that meet standards: they enable the construction of structurally sound free-form buildings, and they're constructed from as few different types of modules as attainable. Divided into elements, it provides Pipe-Z (PZ) and Truss-Z (TZ) structures. PZ is extra primary and types spatial mathematical knots by way of assembling one form of unit (PZM).
