The efficiency of using wide flange (Wf) beam dimensions against stiffness of building structures with the addition of shear wall elements.

The effect of reinforcement on the behavior of building structures such as houses, hotels, hospitals, offices, and others are very high. The existing BPJN Aceh building consists of 7 floors including the ground floor and the roof floor. This study aims to analyze the strengthening of building structures that are more economical with the addition of shear wall elements to the load combination and evaluate their stiffness. The main office building has 2 (two) towers in the form of an elliptical circle on the ground floor with a reinforced concrete structure, while on the first floor to the roof floor it is a steel structure. The calculation of the load used is following the data obtained from the planning consultant. Another factor that is reviewed is the displacement and force on the building before and after adding a shear wall to the structure of the center of the building and evaluating the efficiency of using WF2 as the main beam structure of the building. From the results obtained, the bending moment capacity of beams with shear wall elements is quite good. The ratio between load and resistance capacity ranges from 0.66 – 0.70. For the dimensions of the beam that have been reduced in this study, it turned out to produce a large bending moment of resistance. The ultimate moment in the shear wall is smaller because the system is stiffer and more robust. This is because of the lateral restraint, namely the shear wall. [ABSTRACT FROM AUTHOR]
