Abstract

Direct Displacement Based Design (DDBD) is a new method in computing the loading of earthquakes resistant building structures with displacement as a performance target, which is considered to be more efficient than the method often used previously, namely the Force Based Design (FBD). The purpose of this research is evaluate the performance of the Lampung Regional Police Headquarters building based on the ATC-40 and FEMA 440, where the dimensions of the structure used from shop drawings and can be change if the dimensions not meet requirements. The loads used are gravity loads and base shear force designed using DDBD, where the design performance target is life safety. In the evaluation process of this research, there is one type of main beam that must be changes in dimensions, and the result of structure performance evaluation is immediate occupancy, based on ATC-40 and FEMA 440. Keywords: Displacement, DDBD, Evaluation of Performance.

Abstract

The flate plate is a thick, evenly solid concrete plate that transfers the load directly to the support column without the aid of a beam or shear head or drop panel. This type of plate can be made quickly because of the formwork and simple reinforcement arrangement.  The flate plate is planned to be uniform with dimensions of 5000x4000 mm as many as 9 panels, plate thickness of 150 mm with 25 MPa concrete quality, quality of reinforcement 280 MPa and based on the provisions of SNI 1727; 2013 and SNI 2847; 2013. Flat plate analysis uses the equivalent frame design method, finite element method and SAP 2000 and Microsoft Excel programs. Based of the results of the analysis, the comparison value of moments between the portal method equivalent to SAP 2000 is equal to, whereas between finite element methods and SAP2000 is equal to. In the reinforcement plan, the number and diameter of the reinforcement were obtained in terms of the greatest moment value resulting from the analysis of the equivalent frame design method Keywords: Flat plate, Equivalent Frame Design Method, Finite Element Method

Abstract

The increasement and development of economic growth in Indonesia cause increasement of the construction of warehouse to support business expansion. However, there is an opinion about expensive steel prices which is causes the use of the steel its self is not optimum. In this case, there must be a calculation to determine the model of gable frame and the dimension of steel profiles for the warehouse.  In this study, the frame model is limited of four types that have differences in haunch span.  This study also use the Direct Stiffness Method to calculate structural analysis and  SNI 1729: 2015 to calculate section analysis.  From structural and section analysis, obtained weight for each type of frame.  Frame Type 1 has 4.771,89 kg, Frame Type 2 has 3.348,18 kg, Frame Type 3 has 3.682,24 kg and Frame Type 4 has 10.541,1506 kg.  Based on the volume and weight calculation in each frame type, Frame Type 2 has the lowest weight. Hence, this type of portal can be considered as the most optimum portal type. Key word : gable frame construction, SNI 1729: 2015, Direct Stiffness Method

Abstract

Indonesia is an archipelago and has an important role connecting bridges between islands . Theneed for long -span bridges and lightweight materials and consist artistic value , then the arc steeltruss bridge is an alternative of the problem. In this research will focus on the type a half througharc.The bridge is design to 120 m,span and 12 m,height with a transverse dimension of thevehicle floor complete with sidewalk is 11 m to 2 lanes 2 -way with pavement width of 1 m .Loading calculations used in the planning of the bridge is based on the regulation BMS 1992 andRSNI T - 02-2005 and calculation of the power structure refers to RSNI T - 03-2005 and SNI 03-1729-2002.The results of the study are obtained composite vehicle floor plates , with a reinforced concreteslab thickness of 250 mm . Transverse girder and longitudinal girder using iwf.900.300.28.16iwf.400.200.13.8 with BJ 55. The connection between the ransverse girder and longitudinal girderusing bolts with A325 quality with a diameter of 25 mm with 10 mm thick plate BJ 34. The mainstructure of the arc in the form iwf.400.400 .21.13 . The main structure connection using bolts withA325 quality with a diameter of 35 mm with 2 5 mm thick plate BJ 5 0 .Keywords : bridge , A - Half Through Arch , steel
