关于砖砌体中心受压时变形模量E的研究,过去国内曾作过一些试验,但资料不多,不能满足日益发展的土建事业的需要。1972年我们曾在砖砌体的强度试验中,测量了试件的纵向压缩变形,得到了砌体变形模量E的有关数据,现将资料整理如下;一、试验情况简介试验试件是用100号机制红砖,25号水泥、白灰混合砂浆砌成。断面为24×37cm,高72 cm,共50个。其中有5个试件的砂浆标号R_2经测定过低,故在整理资料中舍去。所有试件全部砌筑在静力试验台上,由千斤顶加荷,每级2吨,在三分钟内变形不再
As for the research on the deformation modulus E of brick masonry center under pressure, some experiments have been done in the past in China, but there are not enough data to meet the growing needs of civil engineering. In 1972, we measured the longitudinal compression deformation of the test piece in the strength test of the brickwork and obtained the relevant data of the deformation modulus E of the masonry. The data is now collated as follows: I. Introduction to the test case The test sample is used No. 100 red brick, No. 25 cement and white ash mixed mortar were built. The section is 24×37cm and height is 72cm, with a total of 50. Among them, the mortar number R 2 of 5 specimens was determined to be too low, so it was discarded in the data. All test specimens were built on a static test bench, loaded by jacks, 2 tons per level, no longer deformed in three minutes
