节能砌块隐形密框结构是一种轻型、节能、经济、抗震的全新结构。对6片节能砌块隐形密框墙板1/2模型进行了拟静力试验。对模型的墙板开裂过程及裂缝发展规律的试验结果进行了分析并与空间有限元弹塑性分析结果进行了比较。分析和比较表明,有限元分析结果与试验结果吻合较好,空间有限元弹塑性分析可用于该结构的设计;可以考虑通过参数优化以达到该结构墙板合理的构造组合;隐形密框采用钢筋混凝土作材料是合适的;墙板在较小的配筋率情况下可以满足承载力需求。
Energy-saving block invisible frame structure is a lightweight, energy saving, economic, seismic new structure. Quasi-static tests were carried out on 1/2 energy-saving masonry invisible and close-framed wallboard 1/2 model. The test results of crack initiation and crack propagation in the model are analyzed and compared with the results of space finite element analysis. The results of analysis and comparison show that the finite element analysis is in good agreement with the experimental results, and the finite element analysis can be applied to the design of the structure. The structural optimization can be achieved through parameter optimization. Concrete is suitable for the material; wall with a smaller reinforcement ratio to meet the needs of bearing capacity.
