【摘要】 对静载作用下的高强钢筋混凝土梁与普通钢筋混凝土梁进行了对比试验研究,验证了高强钢筋混凝土梁能够更好满足正常使用极限状态要求,并将高强钢筋混凝土最大裂缝宽度计算公式进行改进,对平均裂缝间距计算提出了新的建议。经检验计算表明,改进后的计算结果与试验吻合良好。更多还原

【Abstract】 Both high-strength reinforced concrete beams and ordinary reinforced concrete beams under dead loads are tested and studied in this paper. It is validated that high-strength reinforced concrete beams can better meet the requirements of extreme limitation in common use. The paper also develops the formulae for the calculation of the cracking width,and suggests how to calculate the average distance of cracking. All the results obtained in the light of the mended formulae are found to be in good agreement with those of the tests.更多还原
