Deteksi kerusakan struktural penting dilakukan untuk mencegah terjadinya kegagalan struktur dan menambah usia layan bangunan. Salah satu metode untuk mendeteksi kerusakan struktur adalah melalui analisis dinamik, di mana perubahan respons dinamik mengindikasikan perubahan kondisi struktur. Dalam penelitian ini dilakukan pendekteksian lokasi kerusak...
One of important aspect in Structural Health Monitoring System (SHMS) is the initial condition of the structure. This paper studies the initial condition of light rail train (LRT) bridges before officially operated. There are four bridges to be evaluated, consists of three simple supported bridges and one continuous bridge. Data measurement was usi...
Comfort is one among several aspects in building design. Comfort of the occupant can be measured from the dynamic performance of the building during earthquake. This performance can be increased by installing vibration control to reduce dynamic responses of the building.
Considering the space-use efficiency, the building is utilizing certain floors...
As the need of the train speed increased, the existing bridges need to be evaluated, especially in dynamic responses, which are deformation and acceleration. In this study, Cisomang Bridge is modeled and analyzed due to the high-speed train SJ X2 in varying speeds, 50 km/h, 100 km/h, 150 km/h, and 200 km/h. The used of tuned mass damper also will b...
Regardless to the service lifetime of a structure, unwanted vibration can occur due to unknown sources. Excessive vibration may lead to uncomfortable feeling of the occupant, or deterioration of sensitive instruments in an industrial building. To determine the nature of the mentioned vibration problems, an evaluation of dynamic properties of the st...
Wood as a light and green material became one of the choice in civil engineering construction. Since Indonesia is in the active seismic area, the building must have the capability to resist the earthquake loading. The cross laminated timber (CLT) shearwall is the one of the recent development in timber engineering, this CLT is normally using adhesi...
Since the recent development of Cross Nail-Laminated Timber (CNLT) shearwall, the connection between CNLT wall panel and frame or foundation needs to be developed. In this research the CNLT panel connected to the frame or foundation using steel angle with lag-screw fastener. Twelve specimens of steel angle connection using lag-screw fastener was te...
The fabricated cross nail-laminated timber floor was analysed and tested under both non-destructive vibration test and destructive static two line loading test. The six cross nail-laminated timber floor specimens was made from hardwood fast growing species, Albizia falcata. The thickness variation of the floor was made from three and five layers of...
Composite action between plywood and meranti-stringer connected with strong-epoxy glue was analyzed and tested under both non-destructive and destructive test. Three stress skin panel floor specimens were tested under dynamic vibration test, static uniform and line loading. The destructive test using line load was done to observed the ultimate stre...
Dieser Beitrag gilt dem Problemkreis “Abtragung von Längskräften auf Eisenbahnbrücken mit durchgehend geschweißtem Gleis”. Im Mittelpunkt stehen dabei die zusätzlichen Beanspruchungen zu den jahreszeitlichen Temperaturveränderungen, die sich bei der Zugüberfahrt infolge des Steifigkeitswechsels der Kopplung zwischen Gleis und Brückentragwerk ergebe...
Stresses in continuously welded rails on bridges are strongly influenced by the coupling interface between track and bridge in longitudinal direction.Due to European codes this coupling is characterized by a nonlinear stiffness and by a significant dependence on whether the track is loaded by a train or not. The effect of the sequence ‘track unload...
For continuously welded rails the longitudinal track–bridge interaction plays an important role. The coupling between track and bridge consists of a ballasted interface or a slab track with rail–pads.
European codes describe this coupling by means of a bilinear force–displacement relation with making a difference wether the track is loaded or not....
Die Verwendung von durchgehend geschweißten Schienen auf Brücken führt zu zusätzlichen Längsspannungen infolge der Lastfälle jahreszeitliche Temperaturänderung, Brückendurchbiegung und Bremsen/Anfahren. Diese drei Lasten sind durch den Eurocode 1 vorgegeben und in die nationale deutsche Norm DIN Fb-101 integriert. In dieser Arbeit wird erstmals ein...
