Abstract: The elastic behavior of structure is very much dependent on the type of material used and the connection applied. Material properties significantly affect the elastic characteristics of the connection system, and hence it’s structural behavior. The bamboo connection, which is a connectivity system among bamboo stems, have different elastic characteristics depending on the constituent material and the applied connection method. This paper presents the results of study on the elastic behavior of bamboo connection system with the addition of wooden clamps. Model of bamboo connections was made and loaded under quasi-static load, where loading applied repetitively at static load below the proportional limit. Loading was gradually increased at constant additional load in one loading direction. These quasi-static tests were carried out on several specimens of 45o stem angle’s bamboo connection. Two variation loading limits were considered, namely 0,45Pprop and 0,7Pprop. The test results show that the load repetition in quasi-static testing can reduce the connection stiffness by 2.45% and 23.26% respectively. It can be concluded that under repetitive loading, higher load limit might result in larger stiffness reduction. This might be attributed to earlier loss of static friction at higher load limit under loading.
