Abstract

In designing the structures of a building, the beam-column connections are a very important component that needs to be properly taken into account. Failure of these connections can cause total collapse of a building. With the assistance of finite element modeling (FEM) programs such as Idea StatiCa, connections to steel structural buildings can be evaluated quickly. The study was carried out on the Sarinah transformation parking buildings in Jakarta. Based on spectral response analysis, building has been reliable to the latest regulations. The building structure model was tested for horizontal and vertical irregularity factors, story drifts, P-Delta effect, stress ratio of beam and column elements, Strong Column-Weak Beam ratio (SC-WB) and the structure performance levels through pushover analysis, all of which met the requirements. Analysis results showed that based on the plastic moment data, maximum stress at plate was 400 MPa (for x- direction) and 377 MPa (for y-direction). Meanwhile, based on Idea StatiCa analysis, maximum stress at plate was found to be 199.8 MPa (for x-direction) and 81.3 MPa (for y-direction). The plate stress in plastic condition appears to be greater, this is because internal forces acting in this condition are also greater.
