Shear tab connections are some of the most and simplest connections are used on steel constriction. The behavior of shear tabs under conventional loads are studied, but, the behavior of shear tabs become complex under companied loads axial and shear forces and moment. The connection should be sufficient ductile rotation to resist the unexpected force when the structures are exposed such as earthquake or wind load. The aim of this study is tested six steel portal frames. Three specimens are tested under horizontal cyclic load-quasi static load and other three specimens are verified under inclined cyclic load – quasi-static load. The connections of specimens are developed by using composites steel bolt/rubber are instead of conventional steel bolts for bolted the shear tab connections at the web of the beam. The composite steel bolts/rubber with different diameters are made of steel bolts covered by rubber taken from the old and wasted tires. Enhanced in the steel connections were cleared by increasing the resistance of these steel frames during the test as well as the tests are investigated that the effect of the inclined cyclic load is more influential than horizontal cyclic load.
