Finds documents with exactly this word group, in exactly this word order and spelling (e.g. "employer branding").
Finds documents with both search terms (e.g. sales AND bonus).
Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

This chapter delves into the optimization of structural elements, focusing on reinforced concrete slabs, beams, and columns. It explores the cost optimization of solid and waffle slabs, revealing that solid slabs are more economical for shorter spans, while waffle slabs become advantageous for longer spans due to their lighter weight and reduced concrete volume. The analysis extends to reinforced concrete beams, steel beams, and composite beams, highlighting the cost advantages of composite beams over steel-only beams. The chapter also investigates the optimization of column sections, emphasizing the importance of concrete strength and cover in enhancing durability. Additionally, it addresses the conflict between cost minimization and constructability, advocating for multi-objective approaches to achieve balanced design solutions. The studies presented provide practical guidelines for structural design, although they acknowledge limitations and suggest future research directions to incorporate additional criteria and sustainability-oriented strategies.
