Abstract |
The purpose of this study is to analyze the flexural behavior of prestressed half PC slab. For this purpose, construction load tests of
pre-composite PC slabs and the flexural performance tests of composite PC slabs were conducted. The specimens were constructed in full
scale size and bundled rebar were used for full scale load test. Construction load test was conducted over a full span using bundled bars and
the flexural performance test was conducted by 4 points loading test. As a result of construction load test, it was confirmed that the
deflection-span ratio is lower than the current structural design standard (KBC2016). Therefore, it was expected that construction will be
possible without any support. The results of the flexural performance test showed that the maximum allowable deflection was satisfied under
the service load and design load. In addition, no stiffness degradation was appeared until the time of the nominal flexural strength. Therefore,
all of the test specimens in this study were considered that composite PC slab strength were higher than nominal flexural strength. |
