"ABSTRAKThe current design practice for concrete bridge decks requires a top mat and a bottom mat of reinforcing bars. The chloride attack of the top mat reinforcing bars is a major cause of deterioration of bridge decks. Emprical evidence has indicated that the top transverse reinforcing bars can essentially be eliminated without jeopardizing the structural integrity of a deck. To explore this issue, the behavior of a four-span highway bridge deck subjected to a test truck and normal traffic loads is being investigated. The behavior of the bridge under the test truck and various combinations of truck loads has been analyzed with the finite-element method. These result confirm the fact that a properly designed bridge deck does not requiere top transverse reinforcement for sustaining the negative bending moment induced by traffic loads. "

It comprises plenary, invited, and contributory papers covering numerous applications from a wide spectrum of areas related to structural engineering. It presents contributions by academics, researchers, and practicing structural engineers addressing analysis and design of concrete and steel structures, computational structural mechanics, new building materials for sustainable construction, mitigation of structures against natural hazards, structural health monitoring, wind and earthquake engineering, vibration control and smart structures, condition assessment and performance evaluation, repair, rehabilitation and retrofit of structures. Also covering advances in construction techniques/ practices, behavior of structures under blast/impact loading, fatigue and fracture, composite materials and structures, and structures for non-conventional energy (wind and solar), it will serve as a valuable resource for researchers, students and practicing engineers alike."

"Penelitian ini membahas mengenai perbandingan desain antara struktur dengan perletakan biasa dengan yang menggunakan base isolation (High Damping Rubber Bearing). Faktor-faktor struktural tersebut adalah metode desain (Strength Based Design dan Performance Based Design), basement, dan pengaruh P-Delta. Struktur dengan perletakan biasa didesain dengan Sistem Rangka Pemikul Momen Biasa (SRPMB) dan Sistem Rangka Pemikul Momen Khusus (SRPMK), sedangkan struktur dengan base isolation didesain dengan metode Strength Based Design dan Performance Based Design. Dari hasil penelitian menunjukkan penggunaan base isolation dapat meningkatkan periode getar. Struktur terisolasi dengan metode Strength Based Design dapat mengurangi gaya gempa, displacement, simpangan antar lantai, dan rasio tulangan, dibandingkan dengan struktur SRPMB (konvensional). Pengaruh P-Delta memberikan tambahan gaya geser pada struktur terisolasi, dan penambahan basement dalam modelisasi struktur dapat mengurangi gaya geser struktur secara signifikan.

This study discusses the design comparison between structure with conventional restraint with the use of base isolation (High Damping Rubber Bearing). Those structural factors are design method (Strength Based Design and Performance Based Design), basement, and effect of P-Delta. Structure with regular restraint is designed with Ordinary Moment Resisting Frame (OMRF) and Special Moment Resisting Frame (SMRF), while structure with base isolation is designed with Strength Based Design and Performance Based Design method.

The results shows that the use of base isolation can increase the natural period of structure. Isolated structure with Strength Based Design method can reduce the earthquake forces, displacement, story drift, and rebar ratio, compared with conventional OMRF structure. The effect of P-Delta provides additional shear forces on the isolated structure and the addition of basement in structural modeling can significantly reduce shear forces on the structure."
