Abstract

Fire occurring in the building can cause fatal effects to the strength of building. Therefore, this research aimed at investigating the structural strength and capacity pre-fire, the remaining strength and capacity post-fire, and the structural strength and capacity after adding steel plate reinforcement. The field data involved the building of Tamansari Emerald Surabaya Apartment. The nominal moment of beam was controlled pre-fire and post-fire. The results of research demonstrated that the beam encountering fire would have moment capacity reduction at 300°C, 600°C, and 800°C by consecutively 0,0677%, 2,7569%, and 33,98% of the moment capacity in the normal condition. Furthermore, the reinforcement applied steel plate having the dimension 150×5 mm. Thus, the increasing moment capacity after adding reinforcement gained around 60 – 380 Kn.m.

Abstract

The need for earthquake resistant buildings in Indonesia is something that needs to be considered. Considering that Indonesia is an earthquake prone area. A building structure must be designed to be able to withstand lateral loads such as earthquakes within the limits set by the code/standards. For conservative reasons analysis of the P-Delta Effect needs to be considered because the building development ratio will always increase every time. according to SNI 1726-2019 the P-Delta effect is only required for the design of tall buildings. In this case, the P-Delta effect will be calculated in the modeling of non-high-rise buildings and get the results that P-Delta Effect increased story forces: moment of the building under 10%.

Abstract

Kepemilikan kendaraan yang tiap tahun bertambah dan kenaikan tarif angkutan umum menjadi salah satu penyebab menurunnya jumlah pengguna angkutan umum. Tarif merupakan salah satu hal yang penting dalam menentukan suatu daya tarik penggunaan angkutan umum. Penetapan tarif harus memperhatikan daya beli pangsa pasar dan kemauan membayar tarif dari pengguna angkutan umum. Kemauan pengguna untuk membayar tarif sesuai dengan pelayanan yang tersedia dan kemampuan secara finansial yaitu WTP (Willingness To Pay). Kemampuan membayar oleh pengguna angkutan umum terhadap pelayanan yang diberikan berdasarkan jasa pelayanan yang diaggap ideal dan sesuai dengan ongkos perjalanan yang dilakukan yaitu ATP (Ability To Pay). Permasalahan yang timbul jika nilai ATP dan WTP lebih rendah dari tarif angkutan saat ini. Dalam penelitian ini menggunakan 2 jenis kuesioner yaitu ATP dan WTP untuk mengetahui kemampuan dan kemauan membayar jasa angkutan dan untuk mengetahui keinginan masyarakat terhadap tarif yang berlaku. Frekuensi penumpang dalam penggunaan bus lebih dari 3 kali dalam satu bulan hal ini dibuktikan dari hasil kuesioner sejumlah 67%. Berdasarkan hasil perhitungan didapatkan nilai ATP sebesar  Rp 7.625 pengguna Bus Bratang-Bungurasih lebih besar dari tarif saat ini. Dari hasil perhitungan kemauan membayar (Willingness to Pay) apabila adanya peningkatan layanan, pengguna angkutan umum bersedia membayar lebih sebesar Rp 7.190.

Abstract

Bridge damage often occurs, as a result of damage to the bridge causing financial aspects losses and can also cause fatalities. The causes of the damage various factor, one of which is the bridge structure experiencing fatigue. This fatigue caused the strength of the structure of the bridge to decrease. Bridge damage due to a decrease in the strength of this bridge structure can impact the bridge to collapse. To minimize bridge damage due to a decrease in the strength of the structure of the bridge there is a need for bridge maintenance and to make it easier in terms of maintenance it is necessary to know the pattern of collapse of the existing bridge. In the analysis of this collapse pattern, a waren type steel continous bridge will be modeled with a span length of 120 meters. This analysis is carried out by giving a static vertical load at a reference point on the bridge frame, where the load is increased by multiplying until the structure is demage. The results of the study show that in the waren type continuous steel truss bridge failure occurs at the final portal diagonal element in the 2 middle positions. Based on FEMA 356 displacement target, the level of structural performance shows the bridge model under IO conditions and based on SNI 2833-2008, the actual ductility that occurs has met the requirements.

Abstract

The needs of Indonesian people for places to live and work keeps increasing along with the improvement of its population growth. Unfortunately, the areas for developing buildings get decreasing. One of solution for overcoming this problem is by conducting vertical development such as building an apartment. Many apartments with various innovations have been developed by developers to attract consumers such as the existence of swimming pool on the top of building. However, this sort of vertical development plan is very prone to earthquake as Indonesia has high potential of it. This research analyzed the structural behavior of buildings with and without swimming pool. In addition, it analyzed the need of reinforcement for apartment building structure with swimming pool on the top of building toward the seismic load based on SNI 1726:2019. The analysis of seismic load employed spectrum response method. Meanwhile, the need of reinforcement was analyzed based on the plan of dual system by combining Special Moment Resisting Frame System and Special Structural Wall System. The control upon the structural behavior involved the provision of greater drift and period of building structure with swimming pool than without it. The results of research demonstrated that the need of reinforcement for both floor plate thicknesses was Ø10-100. The needs of beam reinforcement in the dimension 350/500 were 5D19 for pedestal area and 3D19 for ground area. Besides, column 750/750 required reinforcement 28D32, whereas the area of beam-column connections necessitated reinforcement 3 feet Ø16-100. The shear wall in 350 mm thick needed 2 rows reinforcement of 28D36. The wall of swimming pool planned in 150 mm thick required reinforcement Ø10-100. Furthermore, the plate for swimming pool base in 200 mm thick demanded reinforcement of Ø10-50 for pedestal area and Ø10-100 for ground area.
