Abstract: Bamboo is mainly a tropical and subtropical plant which is found adequate in many countries. The strength of bamboo as concrete reinforcement is much lower than steel bar reinforcement. However, one of the merits is a cheap and replenishable agricultural resource and abundantly available. Due to excellent properties like high strength to weight ratio, high tensile strength and free-cutting and processing, bamboo as a potential reinforcement material in place of steel is widely available in concrete structural elements. The present paper introduces some of the existing studies and application technology of bamboo reinforced concrete elements in building structures, such as bamboo reinforced concrete columns, beams, slabs and walls.

Abstract: This paper compares the provisions of near-fault effect factors considered in the representative design codes in the world. It is found that the different codes carry out different near-fault effect values. Chinese, American, and New Zealand seismic design codes clearly present the near-fault effect factors, and Chinese seismic design code relatively presents the smallest near-fault effect values among the three codes. While Japanese code accounts for near-fault effect using empirical method and strong motion evaluation employing earthquake source model. The consideration of the near-fault effects in European Standard is the simplest among the five codes.

Abstract: The correlation between intensity measures (IM) for pulse-like ground motions and nonlinear deformation demand of single-degree-freedom-systems (SDOF) is researched, and the efficiency of IM is described. Based on dynamic time analysis of SDOF systems subjected to 72 pulse-like ground motions, the present study investigates the variation of the correlation coefficient between IM for pulse-like ground motions and maximum nonlinear deformation demand of SDOF with the constant-ductility or constant strength system setting. Linear regression analyses are performed on these results to identify the efficiency of peak ground velocity (PGV) and spectral acceleration Sa(T1), which is used as IM for pulse-like ground motion. The study shows that IM of pulse-like ground motions depend distinctly on the system period, ductility levels and strength reduction factors have important influence on the correlation and dispersion, and Sa(T1) and PGV are relatively the good IM for pulse-like ground motion.
