EXPERIMENTAL STUDY ON COMPRESSIVE FATIGUE CHARACTERISTICS OF CONCRETE FLOATING SUPPORT FOR OFFSHORE WIND PLATFORM BY USING SCALE-DOWN PARTIAL SPECIMENS

<p> In order to clarify the fatigue characteristics of the concrete floating of the offshore wind platform, fatigue loading tests were conducted on the small-scale partial specimens under constant compressive stress condition assuming for the service environment. As a result, the fatigue life was about 10<sup>2</sup> times shorter in water than in air, as in the past researches. In addition, when the stress-intensity ratio of the maximum amplitude was large, the fatigue life tended to be shorter at the joint than at the center. It was found that when the maximum amplitude was 70%, the fatigue life at the joint was one order shorter than that at the center. It is considered that the contact state of the joint surface has a great influence. It was confirmed that the fatigue life of PRC members (<i>f<sub>ck</sub>’</i>= 60 N/mm<sup>2</sup>) can be roughly evaluated by applying the fatigue strength formula in the JSCE specifications.</p>

<p>In this paper, the applicability of two deformation indices related to displacement of concrete members proposed by the authors has been verified for full-scale RC members with shear or bending failure under bilateral loads. These two indices, namely "thickness increment of RC member" assuming out-of-plane shear failure, and a newly proposed index, "relative displacement on compressive edge in RC member", which assumes in-plane shear failure and out-of-plane bending failure, are mainly discussed in this paper.</p><p>As a result, it was revealed that the deformation indices could estimate the failure mode of RC columns with shear failure or bending failure under horizontal bilateral loads. In addition, it was confirmed that one of the indices reached the limit value at about 90% or more of the maximum load, and that the element size dependence was small. It was also found that this index can reasonably evaluate the load carrying capacity as much as or better than the existing strain indices.</p>

<p>Based on the assumption that workers can be made to learn correct test methods by having them understand the importance of adhering to the work items specified in the Japanese Industrial Standards (JIS) and properly understand ing the mechanism of measuring equipment, workers were made to conduct the slump test, air content test, and compressive strength test under conditions deviating from those specified by JIS. Two types of concrete were used, with respective slump of 21 cm and 12 cm. The findings included the facts that the timing of lifting of the slump cone can decrease the measured slump value of fresh concrete by up to 3.0 cm, that the finishing method of the samples placed in the air content tester can cause the measured air content value to vary by up to 1.5%, and that tumbling of specimens prior to concrete hardening can cause reduction in compressive strength by approximately 7% by the material age of 28 days.</p><p>Based on the assumption that workers can be made to learn correct test methods by having them understand the importance of adhering to the work items specified in the Japanese Industrial Standards (JIS) and properly understand ing the mechanism of measuring equipment, workers were made to conduct the slump test, air content test, and compressive strength test under conditions deviating from those specified by JIS.
