The first reinforced concrete high-rise was the 16-story Ingalls Building, completed in Cincinnati in 1903. Greater building height became possible as concrete strength increased. In the 1950s, 34 MPa (5000 psi) was considered high strength; by 1990, two high-rise buildings were constructed in Seattle using concrete with strengths of up to

A typical concrete with a compressive strength of 30 :N/mm^2 30N /mm2 would experience cracking under tensile loading at a stress of approximately 2.5-3.5:N/mm^2 2.5−3.5N /mm2. For this reason, we introduce steel reinforcement as a means of resisting the tensile forces that develop in the concrete cross-section.

Presented in Chap. 1 are a definition of reinforced concrete and a basic synopsis of the mechanics of reinforced concrete. Typical reinforced concrete members and the fundamental roles they play in buildings are discussed. The main purpose of this dis- cussion is twofold: (1) to introduce the types of concrete elements that are covered …

1.1 Introduction. Concrete and reinforced concrete are extremely versatile building materials. Concrete, which essentially is a man-made stone, can take virtually any shape and form the designer envisions. Because concrete is like a heavy liquid when produced, it is poured into a mold and, when hardened, will take the shape of the pre …
