9610474 Epstein There are three primary objectives of this study: To furnish the design community procedures for appropriately incorporating block shear considerations for connections of structural shapes not previously tested (mainly structural tees); to provide further experimental data and analytical evidence concerning the effect that eccentricity has block shear, and; to evaluate the capacity of existing structures. All specimens will be ones that could reasonably be used in an actual design. Various individual parameters of the connection geometry will be varied and both 36 and 50 ksi yield steels will be used. Finite element studies of the problem will play an integral part in meeting the objectives.

9610474这项研究的爱泼斯坦有三个主要目标：提供设计社区的程序，以适当地纳入块剪切考虑，以实现未先前测试的结构形状连接（主要是结构性的TEES）；提供进一步的实验数据和有关偏心率具有阻塞剪切的作用的分析证据，以及；评估现有结构的能力。 所有标本都将是可以合理地用于实际设计中的标本。 连接几何形状的各种参数将变化，并且将使用36和50 kSi屈服钢。 该问题的有限元研究将在实现目标中起着不可或缺的作用。
