The seismic behavior of skewed bridges compared to straight bridges is not well recognized and need more study to investigate itsunique behavior under seismic forces. Much more damage have seen from skewed bridges particularly when its deck rotates in theearthquake. Many causes are involved in this behavior such as columns and piers nonlinear deformation patterns. Through a ModalPushover Analysis (MPA) we will assess the inelastic seismic behavior of reinforced concrete bridges those have skew-angled seattypeabutments. The angle of skewness will change the seismic behavior of this kind of bridges and in this paper this change isexplored with special attention. Maximum nonlinear displacement is sensitive to increase the number of spans and the skew angle ofabutments and piers, but the amount of effects are up to number of spans and angle of skewness. This study showed that as thenumber of spans increases, the deck rotation responses at abutments will be deducted and the adverse effect of skew would subtractedin the bridge.

In this study, synthesis of Au and Au/Ag nano-pigments has been investigated. The results showed that pH controlling agents(PCAs) (NH4OH or NaOH) play an important role on the physical properties of Au/Ag nano-pigments and inks. X-raydiffraction (XRD) patterns indicated that pure metallic phase is formed by NH4OH PCAs. Morphological studies revealed theformation of nanometric spherical particles. The smallest size is belonged to Au particles prepared by NH4OH PCA. Becauseof the comparable hue and saturation of synthesized metallic pigments to the commercial inks, the obtained samples have beenintroduced as a suitable candidate for ceramic ink jet printing for tiles.
