Concrete Shell Structures—Practice and Commentary ACI 334.1R-92

Description 1.1.1 Concrete Shell Structures Thin shells—Curved or folded slabs whose thick-nesses are small compared to their other dimensions. They are characterized by their three-dimensional load-carryingbehavior, which is determined by their geometrical shape, their boundary conditions, and the nature of the applied load.Thin shells are usually bounded by supporting members and edge members. 1.1.2Auxiliary members—Ina […]

Building Code Requirements for Concrete Thin Shells (ACI 318.2-14) Commentary on Building Code Requirements for Concrete Thin Shells (ACI 318.2R-14)

Description For types of shell structures where experience, tests, and analyses have shown that the structure can sustain reasonable overloads without undergoing brittle failure, elastic analysis is an acceptable procedure. In such cases, it may be assumed that reinforced concrete is ideally elastic, homogeneous, and isotropic, having identical properties in all directions. An analysis should

Compaction of Roller-Compacted Concrete 11

Compaction of Roller-Compacted Concrete

Description Roller-compacted concrete (RCC) has become an accepted material for constructing dams and pavements, rehabilitating and modifying existing concrete dams, and providing over-flow protection of embankment dams and spillways. Its pro-duction provides a rapid method of concrete construction similar in principle to soil-cement and other earthwork construction. RCC technology developed considerably in the1980s, after early

Report on Behavior of Fresh Concrete During Vibration 12

Report on Behavior of Fresh Concrete During Vibration

Description At the turn of the twentieth century, concrete was generally placed as very dry mixtures, and was deposited in thin lifts and rammed into place by heavy tampers, which involved extensive manual labor. Typical structures, such as foundations ,retaining walls, and dams, contained little or no reinforcement. The concept of rammed concrete in thin
