This thesis presents optimization of precast reinforced concrete slab design with determined span and live load using geometric programming method. The objective of this optimization is to obtain minimum slab cost per square meter as to optimize the slab thickness and required number of reinforcement. One of the most important components in design precast building system is joint between components. To support and improve the result of optimization, experimental study should be undertaken on precast reinforced concrete slab joint system with its support beam. The concept of joint system in this research is that joint does not need to be designed as strong and as rigid as the cast in-place system. This must be proven to meet design criterias with laboratory test. Experimental study is undertaken for three types of sample test : monolith samples (cast in-place), precast samples with welded joint, and precast samples with hooked joint. Test result of those test show almost similar behaviour. Other important result of the test is that these test did not show any slip on joint-in all samples test. Therefore joint system can be used. Despite differences in failure load, under the services load all system show similar liniear elastic behaviour .
