Abstract

Shear walls in high-rise buildings serve to increase the resistance of high-rise buildings to lateral loads. This study aims to compare the structural performance of an existing 8 (eight) storey building designed as a special moment resisting frame structure against a building designed as a dual system, which consists of: structural vibration time, base shear force, displacement, and drift. Three configurations for shear walls are designed, as follows: (1) L-shaped located at the corner of one side of the building, totaling 2 (two) units (SW1); (2) L-shaped located at the four corners of the building totaling 4 (four) units (SW2); and 3) I-shaped located along the side of the building totaling 6 (six) units (SW3). Simulations are run using the Etabs by taking into account dead loads, live loads, and earthquake loads. The results show that the addition of shear walls can: (1) reduce the vibration period of the structure up to 62,55% in SW3, (2) increase the base shear force up to 86,34% in SW3, (3) reduce peak displacement up to 84,86% in SW3, and (4) reduce the drift between floors up to 89,58% in SW3. However, the SW2 is considered to be better applied to the building by taking into account the structural performance, effectiveness and efficiency factors.

Abstract

Abstrak:Akibat pandemi covid 19 pelaksanaan proyek konstruksi mengalami keterlambatan. Penelitian ini bertujuan mendiskripsikan sejauh mana para pelaksana konstruksi yang melanjutkan pekerjaanya dengan menerapkan standar new normal di Kota Malang. Sejauh penelusuran penelitian jenis ini belum pernah dilakukan. Populasi dan sampel purposive [10] tenaga kerja proyek, yaitu: 1) Bangunan gedung 30 orang dan 3) Bangunan perumahan 30 orang. Jika penelitian ini berhasil, maka bisa dipakai rujukan pemerintah daerah maupun owner untuk bahan pertimbangan pengambilan keputusan serta penelitian lebih lanjut. Kesimpulan:(1) Penerapan new standar normal covid 19 pada lingkungan proyek konstruksi bangunan gedung akumulasi rerata sebesar 89,00 % katergori bahaya terhadap penyebaran covid 19, (2) Penerapan new standar normal covid 19 pada lingkungan proyek perumahan kumulasi sebesar 61,73 %, katergori bahaya terhadap penyebaran covid 19 dan (3) Terdapat perbedaan yang signifikan penerapan standar normal new covid 19 pada proyek konstruksi bangunan gedung dengan lingkungan proyek perumahan dan sama- sama berbahaya terhadap penularan covid 19.Kata-kata kunci: penerapan, standar, new normal, proyek konstruksi dan perumahanAbstract: Due to the covid 19 pandemic, the implementation of construction projects has been delayed. This study aims to describe the extent to which construction workers continue their work by implementing new normal standards in Malang City. So far, research of this type has never been carried out. Population and purposive sample [10] project workforce, namely: 1) 30 people in buildings and 3) 30 people in residential buildings. If this research is successful, it can be used as a reference for the local government and the owner for consideration in decision making and further research. Conclusion: (1) The application of the new normal covid 19 standard in the building construction project environment accumulated an average of 89.00% in the hazard category for the spread of covid 19, (2) The application of the new normal covid 19 standard in the cumulative housing project environment was 61.73% , the hazard category for the spread of covid 19 and (3) There is a significant difference in the application of the new normal covid 19 standards in building construction projects with residential project environments and are equally dangerous to transmission of covid 19.Keywords: application, standards, new normal, construction and housing projects

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.
