Abstract

The development of housing infrastructure in Indonesia, including in Tegal Gondo Village, Karangploso, Malang, has attracted people to develop multiple levels house. However, the fluctuating soil conditions (groundwater level fluctuating) became a problem because several houses had cracks in the sloof and walls. Therefore, shallow foundation planning needs to be done by considering the reduction coefficient of soil bearing capacity. This research involved field data collection, laboratory testing, and analysis using Plaxis Version 8.2 software and manual calculations using the Terzaghi formula. The results showed a φR value (reduced soil carrying capacity) of 0.64 at a depth of -1.00 m, and a φR value of 0.55 at a depth of -2.00 m.

Abstract

Indonesia is located on 3 large tectonic plates, making the Indonesian region vulnerable to earthquakes. To overcome this, it is necessary to plan buildings that are earthquake resistant. High population growth has resulted in many different models of tall buildings. These diverse building models have led to the emergence of irregular building designs, both horizontally and vertically. This irregularity can affect the results of structural analysis of earthquake loads. This research discusses the effect of horizontal irregularities in buildings on earthquake loads with the results of research that regular buildings have structural stiffness properties that are relatively stiffer than irregular buildings. In addition, irregularities also result in smaller deviation values ​​between floors in the X direction and larger in the Y direction when compared to irregular.
