Journal of Civil Engineering Vol 29, No 1 (2009)
Publisher : Institut Teknologi Sepuluh Nopember

Performance-based design is becoming increasingly popular in designing a seismic resistant building. In the study, a twelvestory, reinforced concrete office building with asymmetric configuration using dual system located in seismic zone 6 was designed conforming to the Indone sian S e i smi c Code SNI 03-1726-2002 and the Indonesian Concrete Building Code SNI 03-2847-2002. The seismic performance of the building was evaluated using the Static Nonlinear (Pushover) Analysis and Inelastic Dynamic Time History Analysis. The performance point obtained from the pushover analysis was defined using various methods, such as FEMA 356, ATC-40, FEMA 440, and SNI 03-1726-2002. The result of the study indicated that the highest performance point was that obtained according to FEMA 356 and FEMA 440, whereas the lowest value was that in accordance with SNI-03-1726-2002. The roof displacement difference of that obtained from El-Centro dynamic analysis and performance-point pushover analysis can reach up to 5 cm and 2.4 cm in X- and Y-directions, respectively. This indicates that the pushover analysis is quite accurate for evaluating the corresponding building since the first mode shape is quite dominant.

This study investigates on household factors which influence motorcycle ownership in Denpasar city, Bali by using a multinomial logit model. The analyses show that the number of family members were about 0.83 and 2.6 times more likely to own, respectively, two and three motorcycles or more than one motorcycle. Total household income of less than one million rupiahs and between one and two million rupiahs were respectively 83.7 and 84.7 percents less likely to influence three motorcycles or more than one motorcycle ownership. Meanwhile, due to its high maneuverability on the congested road, a household was about 3.3 times more likely to own three motorcycles or more than one motorcycle. The probability analyses present that a double change in number of family member could influence one, two, and three motorcycles ownership or more by 19, 34, and 48 percents, respectively.

MODIFIED FIXED-ANGLE STRUT-AND-TIE MODEL FOR HIGH STRENGTH REINFORCED CONCRETE BEAMS Tavio Tavio
Journal of Civil Engineering Vol 29, No 1 (2009)
Publisher : Institut Teknologi Sepuluh Nopember

Nonlinear finite element analysis was applied to various reinforced concrete beams using a set of constitutive models established in the modified fixed-angle softened-truss model (MFA-STM). The model was implemented by modifying the general-purpose program FEAPpv. The model can take account of the six important characteristics of cracked reinforced concrete: (1) the softening effect of concrete in tension-compression; (2) the tension-stiffening effect of concrete in tension; (3) the average stress-strain curve of steel bars embedded in concrete; (4) the shear modulus of concrete; (5) the aggregate interlock; and (6) dowel action. The comparison shows the aggregate interlock and dowel action can reduce the overestimation of the shear capacity of high strength reinforced beam, especially the high strength reinforced deep beam without web reinforcement. Moreover, the model is suitable for being implemented numerical procedures due its simplicity.

Utilization of waste aggregates for construction industry had been encouraged in line with increasing pressures to reduce exploration of natural aggregates. One alternative material that can be used as masonry block unit is the construction demolition waste (CDW) with asphalt as the binder (CDW block). The objective of this paper is to produce CDW block with a performance equal to the concrete block commonly used in the United Kingdom with a compressive strength between 3.5 MPa and 7 MPa and the specific creep strain less than 100 microstrain. The CDW block requires suitable particle size proportion, in order to obtain satisfactory results and to meet the demand of using minimum bitumen content and low compaction level. The CDW block requires sufficient heat curing to harden the asphalt. It was found that CDW materials were a very suitable material to be used for making CDW blocks. Compaction level of 2 MPa and curing regime of 200°C for 24 hours were sufficient and gave satisfactory results.

Publisher : Institut Teknologi Sepuluh Nopember

Scour is a natural phenomenon caused by erosion due to water flow on the alluvial channel bed and channel wall. In fact, scour happened in the bridge abutment is total scour, that is a combination between local scour, general scour, and constriction scour. This research aims to find the depth of scour near abutment in clear-water scour condition. This research was carried out using recirculation flume. The channel model was a compound channel and using steady-uniform flow. The abutment model was Spill-Through type (ST). The depth of scour near abutment was measured in each 6 hours running at 9 point of position. The research result shows that the maximum scour depth happened at point of separation. The depth of scour is mostly affected by Reynold and Froude number of flow. In general, the scour pattern happened around abutment is the same at every running which can be seen in the scour contour pattern that has half horseshoe shape.

This research presents the result of two rectangular filled tube column-to-beam connections under cyclic loading using finite element analysis. Connections of all two models were using weld connection and shear tab attached to beam webs. In this study, 2 models were made: RR-1 and RB-2, which are RCFT connection with RBS and RCFT connection without RBS. This study is conducted to learn, the advantages of RCFT connection with RBS against RCFT connection without RBS. The analysis results observed that cyclic performance of the RBS moment connection was much superior to the connection without RBS. The highest regions of stress occur in vicinity of beam bottom flange near column face for connection without RBS. For connection with RBS, the highest regions of stress occur in reduced beam section of the beam
