Abstract

Vibrations in certain building floor plate systems are excitations that arise from rhythmic human activities such as running, dancing and aerobic movements. The term “frequency content” refers to the number of modes across the floor system frequencies. The first natural frequency (fn), also referred to as the fundamental natural frequency, is used for floor vibrations for design purposes. In terms of fundamental natural frequencies, humans are more sensitive to low frequency vibrations than high frequencies. In response to floor vibrations, the human sensitive range is usually between 4 and 8 HZ. Analysis found that the stair floor plate structure with D10-150 floor reinforcement could withstand the design load. The cause of very pronounced vibrations on the stairs is caused by the natural vibration frequency on the stair plate < 8Hz. The selection of reinforcement for the stair floor plate is carried out in the middle of the floor plate span. After recalculating, the additional stiffness of the floor plate produces a vibration frequency of > 8Hz, so that the vibrations are no longer disturbing.

Abstract

Differential settlements of foundations in buildings often results in building damage. The first damage appears on the architectural part and then as the difference in settlement increases, it will start to attack the structural part. This increase certainly results in harm to building users. Buildings that use shallow foundations can generally be divided into causes based on soil parameters, soil load on the foundation and the cross-sectional shape of the foundation. Shallow foundations according to Terzaghi, the soil parameters that influence them are the coefficient of cohesion and friction angle plus the specific gravity of the soil which supports the load coming from the building. The foundation cross-section factor is influenced by the depth and width of the cross-section whether it is square, round or continuous. The oblique crack pattern that occurs in the building walls is an indication of differences in settlement in the foundation. This research was carried out by carrying out crack patterns that indicate foundation settlement, analyzing the causes of foundation settlement, and carrying out calculation analysis to determine the strengthening method. The method is carried out by collecting data on the dimensions of the building structure and compiling the parameters used according to loading regulations. The decline was caused by new embankments which were directly loaded and primary consolidation had not been completed, low soil bearing capacity in the surface layer, additional load from the design load.
