ABSTRACT: Tests on twenty-one concrete filled steel tubes to investigate the influence of compaction methods on the strength of concrete filled steel tubular members are reported.

摘要：测试二十一钢管混凝土试验，研究了钢管对混凝土构件强度压实方法的影响报告。

Two parameters were investigated, including slenderness ratio and load eccentricity.

对两个参数进行研究，包括长细比和荷载偏心。

It was found that better compaction of concrete resulted in higher values of the ultimate strength of concrete filled steel

tubular members

结果发现更好的压实混凝土，能够使钢管混凝土有更高的极限强度值。

The tests show the importance of good concrete compaction for concrete filled steel tubes

测试显示良好的混凝土重要性压实的重要性为方钢管混凝土管。Keywords: concretefilled steel tube, column, strength, deflection, concrete compaction

关键字; 钢管混凝土，柱，强度，挠度，混凝土压实

1. INTRODUCTION 引言

Concrete filled steel tubular columns have been used extensively in Europe, Japan, Australia, China, as well as other countries.

在欧洲，日本，澳大利亚，中国，以及其他国家钢管混凝土柱已广泛被使用。

They have proved to be economical in themselves as well as leading to rapid construction and thus additional cost savings.1

他们已经是被证明是经济实惠的，同时也能促进快速建设和增加消费储蓄

In the past, much progress has been made in studying the bond strength between the steel tube and its core concrete, studies

of how the concrete compaction method influences the strength of concrete filled steel tubular members have been seldom made.2–8

在过去的研究中，钢管与核心混凝土之间的粘结强度有了很大进展，但对混凝土的压实方法对钢管混凝土构件强度的研究已经很少了。2–8

These and earlier results show that perhaps the most significant factor influencing the ultimate bond strength might be compaction and the consequent better keying of the concrete with the surface irregularities in the steel.

这些和早期的结果表明，也许最重要的因素可能影响最终粘结强度压实以及更好地键控，因而混凝土与钢管中的表面成不规则性

In Reference (2), specimens have been tested for different conditions likely to arise in the manufacture of concrete as follows:
