The 14th edition of the classic text, "Design of Concrete Structures", is completely revised using the newly released 2008 ACI (American Concrete Institute) Code. This new edition has the same dual objectives as the previous editions; first to establish a firm understanding of the behavior of structural concrete, then to develop proficiency in the methods used in current design practice.
There is a need to focus on understanding the design of special reinforced concrete structures and pre-stressed concrete. Those main items of reinforced concrete structures are widely used in industrial sector, especially in the onshore oil and gas fields. This GL O MACS training course will lead the delegates to the professionality in the design of reinforced concrete for industrial projects
Preload has designed and constructed more than 3,600 prestressed concrete tanks worldwide in its 85-year history. Since the mid-1930''s PRELOAD has been recognized as the forerunner in the engineering and construction of circular prestressed concrete structures.
18/7/2018· The repaired reinforced concrete beam ends were found to be at least as strong as similar beams that were in good condition and had not needed repair. The initial repair methods and subsequent testing of the prestressed beam ends are demonstrated in a video created by the research team (testing starts at 3:30 min).

The prestressed concrete design of a structure is influenced by either of the two processes, pre-tensioning, and post-tensioning. Pre-tensioning can be further classified into two egories such as linear pre-tensioning and circular pre-tensioning. Pre-Tensioning and
The two untopped precast concrete diaphragms of Section 8.1.1 show the requirements for Seismic Design egories B and C using 8-inch-thick hollow core precast, prestressed concrete planks. Section 8.1.2 shows the same precast plank with a 2-1/2-inch
6. Prestressed Concrete: It is a special type of reinforced concrete in which the reinforcement bars are tensioned before being eedded in the concrete. Such tensioned wires are held firm at each end while the concrete mix is placed. The result is that when the
