Objectives: To investigate and compare the ductility performance of precast column foundation connection using method proposed by Park ASCE 31-03. Methods: Strength are most important parameters to resist earthquake forces for overall safety a structure. Evaluating from experiments is cumbersome process. From experimentally obtained load-displacement envelope, was evaluated four specimens Paula...

Progressive collapse starts when any load-carrying elements of the building during extreme loading, such as earthquakes, blasts, or fire. The Precast Steel Reinforced Concrete (PSRC) buildings comprise precast RCC columns and steel girders. These structural are connected to form a moment-resisting frame susceptible progressive collapse. However, this system has advantage inherent stiffness damp...

Precast concrete structure is a low-carbon building system that has been attracting extensive attention in recent decades. Beam–column joints are the weak links precast structures. Past studies showed five-spiral stirrups had excellent confinement effects and potential to enhance seismic performance of This study proposed reinforcement beam–column by using investigated their performance. Consid...

Accelerated bridge construction (ABC) has attracted much attention in China as a new and efficient method. However, the seismic performance of connections between precast piers other structures limits application ABC medium high zones. In this paper, quasi-static test was conducted to investigate differences cap–column socket connection (PSC) specimen, which reinforced an embedded RC column-to-...

Because of the high precision and stability intelligent system, tensioning technology can completely eliminate interference human factors effectively ensure construction quality prestressed tensioning. In this paper, characteristics, principle, process flow points for attention in precast box girder are introduced.

Precast segmental reinforced concrete (RC) piers have been widely used in the construction of offshore bridges to speed up construction. Offshore cold regions are inevitably affected by seawater freeze–thaw cycles under periodic movement tides, which could reduce mechanical property RC piers. Based on low cyclic loading test 12 specimens with different cycles, axial compression ratio, diameters...
