项目摘要

This research was performed for investigating seismic characteristics of precast concrete structures having ductile joint, so-called "device type joint". That research would be important information for establishing seismic design method of ductile joint. This research consists of three parts.Part 1 is research for shear transfer mechanism on crack surface of high strength concrete. On this part, direct shear loading experiments for precast concrete joint made by high strength concrete were performed. From those experiments shear transfer model on crack surface of high strength concrete was got.Part 2 is research for shear transfer mechanism of precast joint using connecting bars under inclined arrangement. On this part, direct shear loading experiments for precast concrete joint having inclined arranged connecting bars were performed. From those experiments precast joint having inclined arranged connecting bars had large ductility and shear strength. It was possible to form ductile precast joint by using inlined arranged connecting bars.Part 3 is research for shear characteristics of crack of column having longitudinal reinforcements which arranged inclined against crack surfaces. That research is application of results of Part 1 and Part 2. Those results were applied for investigation of shear transfer mechanism of reinforced concrete column. From results of experiments about columns, seismic energy assumption on shear crack surfaces made clear by using results o f Part 1 and Part 2.From results of those three parts, it is possible to form ductile precast joint, and some useful suggestion for seismic design method of ductile precast joint were got.

本研究旨在探讨预制混凝土结构具有延性接头（所谓的“装置型接头”）的抗震特性。该研究为延性节点抗震设计方法的建立提供了重要的参考依据。本文的研究工作主要分为三个部分：第一部分是高强混凝土裂缝面剪力传递机理的研究。对高强混凝土预制节点进行了直剪试验。第二部分是斜向布置的连接钢筋预制节点的剪力传递机理研究。在这一部分中，对斜向布置的预制混凝土节点进行了直剪试验。试验结果表明，斜向布置的预制节点具有较大的延性和抗剪强度。采用顺排连接杆可以形成延性预制节点。第三部分研究了斜向布置纵筋柱裂缝的受剪特性。该研究是第一部分和第二部分结果的应用。将这些结果应用于钢筋混凝土柱剪力传递机理的研究。通过柱的试验结果，利用第一、二部分的结果，明确了剪切裂缝面的地震能量假设。通过这三部分的试验结果，说明了延性预制节点的形成是可能的，并对延性预制节点的抗震设计方法提出了一些有益的建议。
