ABSTRACT Recently, displacement-based seismic design concept is being developed. According to this concept, structures are designed based on a certain displacement target. This paper presents the application of the displacement-based design concept to reinforced concrete bridge piers of 3, 5, 7, 9 11,and 13 m height. The design results are then analyzed by inelastic time history analysis using Ruaumoko computer program. The results of inelastic time history analysis show that for bridge piers with height 7 m or more, the actual drifts relatively fit the design drifts, while for the 3m and the 5m height piers, the actual drifts are significantly less than the design drifts.
Abstract in Bahasa Indonesia :
Akhir-akhir ini sedang dikembangkan metode perencanaan seismik struktur dengan konsep berbasis perpindahan. Dengan konsep ini struktur direncanakan berdasarkan target perpindahan yang dikehendaki. Tulisan ini membahas aplikasi konsep berbasis perpindahan pada perencanaan struktur pilar jembatan beton bertulang dengan ketinggian 3, 5, 7, 9, 11, dan 13 m. Hasil perencanaan kemudian dianalisis dengan analisis inelastik riwayat waktu dengan menggunakan program komputer Ruaumoko. Hasil analisis inelastik riwayat waktu menunjukkan bahwa untuk pilar dengan ketinggian 7m atau lebih drift yang terjadi cukup sesuai dengan drift yang direncanakan, sedangkan untuk pilar dengan ketinggian 3m dan 5m drift yang terjadi relatif jauh lebih kecil daripada drift yang direncanakan.

    ABSTRACT: Through the use of moment-curvature analysis of circular bridge columns, dimensionless serviceability and damage control curvature relationships are developed that depend only on the column axial load ratio and section diameter. These relationships are used to establish curvature, displacement ductility, drift ratio, and equivalent viscous damping capacities for the design limit states considered. It is shown that current code-based design approaches, which imply a constant ductility factor, will generally result in damage levels that are highly variable. The paper also discusses implications of the study on limit-states design approaches such as displacement-based design.

    ABSTRACT: This paper presents a seismic design philosophy based on displacements rather than forces. By inverting the seismic design process, a rational method is established where member strength and stiffness depend on the target displacement. A comprehensive procedure for displacement-based design of cantilever bridge columns is presented and verified by dynamic inelastic time history analysis. Parameter studies are used to examine the influence of several variables within the possible design solution space.
