Lightweight steel structure (LSF) is a modern construction method ideal for buildings up to five floors, originating in Canada in the 1950s and gaining popularity in industrialized nations since the 1990s. The core components include thin wall steel sections (LGS) made from thin steel sheets through the Roll Forming process. In this system, vertical elements support both vertical and lateral loads, while horizontal elements, known as runners, play a crucial role in the overall stability and integrity of the structure.

Focusing on civil engineering, this book explores structural control systems designed to mitigate damage from dynamic environmental loads. It categorizes control methods into four types: passive, active, semi-active, and hybrid. Passive systems operate without external power, utilizing the structure's inherent properties or additional devices to reduce vibrations. The book delves into the principles and applications of these systems, providing insights into their effectiveness in enhancing structural resilience.

Strukturelle Kontrollsysteme im Bauwesen sind entscheidend zur Minimierung von Schäden und zur Reduzierung von Energie, die durch dynamische Umweltbelastungen entstehen. Diese Systeme werden in vier Gruppen unterteilt: passive, aktive, semi-aktive und hybride Kontrolle. Passive Systeme, die keine externe Energie benötigen, nutzen die natürlichen Eigenschaften der Struktur oder spezielle Vorrichtungen zur Dämpfung von Schwingungen. Die Unterscheidung zwischen passiven und aktiven Systemen bildet die Grundlage für die Anwendung dieser Kontrollmethoden in der Bauindustrie.

Os sistemas de controlo estrutural na engenharia civil visam minimizar danos e dissipar energia de cargas dinâmicas. Eles se dividem em quatro grupos: passivo, ativo, semi-ativo e híbrido, sendo que os sistemas passivos não requerem energia externa, utilizando as propriedades da estrutura para reduzir vibrações.
