Abstract

This study used an experimental method in the Laboratory of Structural and Construction Engi- neering Faculty, University of Lampung. The test object in this research is a concrete cylinder with a diameter of 15 cm and 30 cm high. And the concrete beam specimen with a length of 60 cm, width 15 cm, height 15 cm. While testing the compressive strength and flexural strength of high strength concrete made fas 0.36 and 0.39 after the test specimen was 14, 28 and 56 days. In testing the compressive strength of concrete fas 0.36 and 0.39, OPC cement concrete without silica fume replacement compressive strength higher than the compressive strength of cement PCC. Value OPC cement with fas 0.36 and 0.39 in the concrete life of 56 days each -masing amounted to 39.7264 and 34.9139 MPa. OPC concrete of cement with silica fume replacement of 10% in test- ing concrete compressive strength fas 0.36 and 0.39, higher compressive strength of cement PCC. The compressive strength of OPC cement with silica fume replacement fas 10% with 0.36 and 0.39 in the concrete life of 56 days each for 33,7816MPa and 30,9507MPa. In the flexural strength testing of concrete fas 0.36 and 0.39, OPC cement concrete without silica fume penggntian strong bending higher than cement PCC. OPC cement flexural strength values with fas 0.36 and 0.39 in the concrete life of 56 days each for 7,3778MPa and 7,6MPa. OPC cement concrete with the re- placement of silica fume 10% in flexural strength testing of concrete fas 0.36 and 0.39, a strong bending higher than cement PCC. Flexural strength value of OPC cement with silica fume re- placement fas 10% with 0.36 and 0.39 in the concrete life of 56 days each for 7,8889MPa and 8,3333MPa.

Abstract

The use of plywood as a construction material to hold the load as the beam has not been widelyused. It is due to little data and information in a plywood timber strength especially against theshear bearing. The research was conducted to determine the strength of the beam composed ofplywood (meranti wood origin) using adhesives Urea Formaldehyde (UF) for shear strength.From the test results show the use of the number of layers of plywood on the beam web's influenceon forces arrayed logs. Average strength achieved in block structured web thickness of 5 cm at2498 kg, 10 cm thick web of 4649 kg and a 15 cm thick web of 4443 Kg.

Abstract

Analysis of the data in this study is focused on a comparison of the results of direct testingdeflection field with SAP 2000 analysis and manual calculation of loading field and standard(RSNI T-02-2005) with a maximum deflection limit bridge.Based on the results obtained by calculation of loading field: percentage reduction of deflectiontest results without the GFRP reinforcement compared to after given the GFRP reinforcement ondirect testing field, SAP 2000 analysis, and manual calculation respectively, they are obtained4.934 %, 0.7097%, and -0,6804 %. Based on the results of the calculation deflection of theloading standard: percentage reduction of deflection test results without the GFRP reinforcementcompared to after given the GFRP reinforcement on SAP 2000 analysis and manual calculationrespectively, they are obtained 2,0212 % and -0.17557 %. The Values of deflection are calculatedstill below 18.75 cm as deflection limit L/240.
