Abstract

Indonesia is a country which is in an earthquake prone area. Earthquake disasters are destructive natural phenomena. The damage caused is very large, especially in the field of steel structures of buildings. The effect of earthquakes is an important factor to planning the design of building structures. Existing buildings are claimed to be earthquake resistant by planners, but not necessarily the results as expected. Along with the development of technological advances in the field of civil engineering, new concepts and methods emerged in the analysis and planning of earthquake resistant buildings, one of which was the concept of Performance Based Seismic Evaluation (PBSE) with static thrust load analysis or Pushover analysis. This method is able to provide information on the pattern of collapse of buildings that exist when burdened with earthquake forces that exceed the capacity of the building, whether direct collapse or building is capable of behaving nonlinear (progressive) before total collapse occurs. The purpose of the final assignment is to evaluate and optimize the performance of the load on the factory building to determine the effective capacity of the structure and behavior by showing the scheme of plastic joints on the beam and column elements with the Pushover method based on the Applied Technology Council (ATC-40) code and determining the level structural performance of earthquake prisoners based on the code. From the results of the study, it was found that the performance point is V = 61.027 Ton and D = 0.074 m. The structure of the building is able to provide nonlinear behavior that is indicated by the initial phase and the majority of the occurrence of plastic joints occurs in the beam element and then the column element. Structural performance levels are included in the Immediate Occupancy criteria, which means that minor structural damage occurs and the building can be reused immediately again.

Abstract

Pelabuhan Tanjung Priok merupakan pelabuhan kelas utama dilingkungan PT. Pelabuhan Indonesia II (Persero). Sebagai pelabuhan terbesar di Indonesia diperlukan fasilitas alat bongkar muat yang dapat mendukung kegiatan operasional berjalan optimal. Agar alat bongkar muat dengan ±100 ton dapat beroperasi di atas dermaga maka perlu diadakan pekerjaan perkuatan dan peninggian dermaga, sehingga dapat melayani kapal dengan draft yang lebih dalam. Oleh karena itu PT. Pelabuhan Indonesia II (Persero) Cabang Tanjung Priok akan melakukan pekerjaan perkuatan dan peninggian dermaga dan lapangan di Dermaga 005, 006 dan 007 Terminal Operasi 1 Pelabuhan Tanjung Priok. Pada proyek ini dalam hal pekerjaan pelat lantai digunakan sistem konvensional. Dan tujuan penelitian ini adalah melakukan komparasi pada sebuah proyek dengan menggunakan kedua metode pelat lantai konvensional dan pracetak agar efisien dalam penerapan sistem, biaya dan waktu. Dari studi yang didapat untuk pekerjaan pelat lantai dengan metode konvensional dan precast didapat efisiensi biaya sebesar 15,308,130.00 atau 29.82% dan mendapatkan efisiensi waktu selama 7 minggu dengan metode precast.

Abstract

Indonesia is an archipelago country located at a meeting of three tectonic plates so that Indonesia has the potential to experience an earthquake. As a result of the earthquake many buildings are damaged building structures. When an earthquake happens, the building is expected to be able to accept a certain level of earthquake force without significant damage to the structure or if the collapsing structures must be able to give non-linear behavior in the postelasticconditions so that the building's safety level against earthquake and safety of the occupants is more secure. The Pusdiklat PPATK boarding house, Depok is a building which in its development planning is expected to be able to accept the earthquake force and behave non-linearly. But this dormitory building does not yet have data on building resistance to earthquake forces. Therefore it is necessary to analyze this building by using one method of building strength analysis to earthquake forces that is pushover method. This analysis is done using SAP2000 program. The conclusion of the analysis shows that the greater the force (base force) given the greater the displacement that occurs in the building. The maximum earthquake load that the building can accept is 730,383 kN. Based on the ATC-40 performance limit the building is at the level of IO, indicating that the building is safe to use during an earthquake.

Abstract

Needs for air transportation cause traffic congestion in air generally perceived as consumers / passenger service users .Often there was an accident in flight , offense an airspace conducted by aircraft that makes passengers not safe. Therefore, it requires a watchtower air traffic or Air Traffic Control (ATC). On ATC Tower case which is a 9 stories building, the lateral retaining structural systems that can be used are shear wall system and without shear wall system. The analysis was performed to get structure behavior differences between two building models and better lateral retaining system for ATC Tower based on its structural behavior. The values of the analysis results shown that the two models are equally good and acceptable based on its torque, shear force, period of vibration, story drift and displacement. However, for ATC Tower case, the structural behavior is better when using shear wall or on 1st modeling because of its smaller moment, shear forces, and displacement.
