Concrete liquid containing structures (CLCS) are primarily used for the storage of water and wastewater and other industrial wastes. These structures are considered as lifeline facilities that require careful design and detailing to meet serviceability requirements for crack and leakage control. A good understanding of the behavior of these structures is necessary in order to meet safety and serviceability objectives while containing construction and maintenance costs. There is a great deal of inconsistency among the design standards for this important broad class of structures. This is mainly due to the lack of understanding of the behavior of these structures under static and seismic loading. There is debate on the validity of some of the provisions in codes and standards in this regard. In recent years, the designers have moved away from the conventional joint detailing due to construction issues. The use of widespread and inconsistent joint details have raised questions on liquid tightness in these structures. The main objective of the proposed research study is to develop a rational design procedure, through experimental programs, for concrete tanks that assures a safe leak resistant structure. The study will be conducted on specimens that are representative of full scaled base slab-wall connection portion of tanks with different connection details. These specimens while under reversed cyclic loading will be simultaneously subjected to liquid pressure and leakage tests. It is expected that this research program will provide a framework to understand the behavior of CLCS under static and seismic loading. This framework will be useful towards the development of design guides for CLCS.

含有混凝土液体（CLC）的混凝土液体主要用于储存水，废水和其他工业废物。这些结构被认为是生命线设施，需要仔细设计和细节以满足破解和泄漏控制的可使用性要求。必须很好地理解这些结构的行为，以便在包含施工和维护成本的同时满足安全性和可维修性目标。对于这种重要的广泛结构，设计标准之间存在很大的不一致性。这主要是由于缺乏对静态和地震载荷下这些结构的行为的理解。在这方面，关于代码和标准的某些规定的有效性存在争议。近年来，由于施工问题，设计师已经离开了常规的关节细节。使用广泛和不一致的联合细节的使用引发了有关这些结构中液体紧密度的问题。拟议的研究研究的主要目的是通过实验程序制定一个合理的设计程序，以确保具有安全泄漏结构的混凝土储罐。该研究将以代表具有不同连接细节的储罐的全尺度基本板壁连接部分进行的标本进行。在反向循环负载下，这些样品将同时进行液压和泄漏测试。预计该研究计划将提供一个框架，以了解静态和地震负载下CLC的行为。该框架对于开发CLC的设计指南将很有用。
