STUDY ON THE FUNDAMENTAL FREQUENCIES OF RECTANGULAR CONCRETE TANKS USING FEM AND ANALYTICAL CODES
Impulsive and convective frequencies are one of the most important subjects for evaluation of the seismic behavior of tanks. These two frequencies are defined by Housner and used for obtaining Rayleigh damping in time history analysis. ACI 350 and NZSEE standards have suggested some analytical solutions for finding convective and impulsive frequencies. These frequencies can also extract from mo...

متن کاملStudy on Aging and Damage Evaluation systemof seepage Control Canal with Concrete
Based on knowing clearly about the goal and principle of the system development, the paper formulated its basic methods and tools as well as the environment of development, studied the structure and the operation procedure of the system. The system also established the database and the evaluation system of the aging and damage situation of seepage control canal with concrete, and therefore impr...
متن کاملFundamental Study on the Development of Structural Lightweight Concrete by Using Normal Coarse Aggregate and Foaming Agent
Structural lightweight concrete (SLWC) has superior properties that allow the optimization of super tall structure systems for the process of design. Because of the limited supply of lightweight aggregates in Korea, the development of structural lightweight concrete without lightweight aggregates is needed. The physical and mechanical properties of specimens that were cast using normal coarse a...
متن کاملPreparation and properties of porous aerated concrete
INTRODUCTION Porous concrete, especially Aerated Autoclaved Concrete (AAC) was first developed by a Swedish engineer between the years 1920 and 1932 [1]. He was searching for a material with the properties of wood, but without the disadvantages of wood. Near the end of World War II, AAC became widely used. Vast areas of cities and industries lay in waste and tremendous rebuilding became necessa...
