The study presents the potential use of Kelud volcano eruptive deposits, Indonesia which includes river sand as fine aggregate, pumice well scoria coarse aggregate green structural lightweight concretes. Their physical properties were experimentally tested and compared with controls that commonly used in region. Furthermore, they applied on concretes designed for five determined compressive str...

It is impractical and uneconomic to design a structure that remains elastic throughout severe ground motions. The main design philosophy is that minor structural damages are acceptable as long as the structure does not collapse. Hence, seismic base isolation of structures provides a better alternative in constructing seismic resistant structures. A fixed-base structure designed in accordance to...

Hybrid connections are a viable solution for erecting precast concrete frame structures in seismic areas. Such type of connections makes use of unbounded post-tensioned strands and partially unbounded mild steel rebars, also known as special reinforcing bars, in order to assemble the precast frame units. The paper presents a study about the nonlinear cyclic behavior of the special reinforcing b...

Research precast beam type L shape has produced strength of flexure where it was jointed at middle span with shape. Problem about and deflection joint Type Aim this research determined such maximal load would be apllicated. Precast consist two P1 P2 were tested point applicated. This have data P2. 28,44 mm maximum 11,21 Ton. 26,71 11,76 Except that data, also chart versus behavior less for duct...
