A scientific and comprehensive method was proposed for quantitative analysis of spalling degree from its mechanism.

例如，英法海底隧道发生的火灾造成隧道内表面高强混凝土爆裂，造成了隧道大面积的受损区域。

However,the increased use of high strength concrete has raised concerns about its behavior in fire,especially the problem of spalling.

但是，与普通混凝土相比，高强混凝土的耐火性能较差，特别是火灾中的抗爆裂性能较差。

Cracking patterns, streel bars's stress distribution and force-displacement curves at beams ends resulted from the experiments indicate that at location of plastic hinge area the main cracks developed sufficiently and the stress of steel bars was peak values, and no bonding failure of steel bars is found within core region of assemblies.

有限元分析所得裂缝分布、钢筋应力分布以及梁端力－位移曲线反映出，高强钢筋混凝土框架梁柱组合件在低周反复荷载作用下梁端塑性铰区裂缝开展充分，钢筋应力最大，核芯区内钢筋未发生粘结破坏。

论文的研究结果可以在一定程度上补充完善了钢管高强混凝土节点的研究方面的不足，为相关研究和设计人员提供参考。

While for the time being the research on joints for high strength concrete-filled steel tubar column-Variable width reinforced concrete beam is preliminary. Based on nonlinear elasto-plastic theory and finite element method analyse, mechanical performance for the joints was studied.

而目前对于钢管高强混凝土柱—变宽度钢筋混凝土梁节点的研究工作尚不完善，因此，本文在非线性弹塑性理论分析的基础上，对该节点的力学性能进行研究。

Based on theory analyse, the three-dimensional finite elemental numerical calculation was carried out on joints for high strength concrete filled steel tubar column- Variable width reinforced concrete beam, the segregate calculational model of rebar steel tube and concrete was adapted..

基于理论分析，本文主要对钢管高强混凝土柱—变宽度钢筋混凝土梁节点进行了三维有限元数值模拟计算。

We also test the relationship between the rope's tenacity elongation and a series of processing parameters, such as twisting pre-tension , count, direction and twist or twistless sub-ply.

通过对加捻预张力、捻度、捻度方向及小支股加捻与否等一系列工艺参数对绳索强伸性能的影响试验，从中得出6mm三股高强涤纶绳较理想的工艺参数，并作了分析。

The adding of mineral admixtures and high performance water reducer is the key factor of preparing self-compacting concrete, especially high strength and extra strength self-compacting concrete. Mineral admixtures have unsuperseded advantages in improving the workability and durability of self-compacting concrete.

加入优质矿物掺合料及高效减水剂是配制免振捣高性能混凝土特别是高强超高强免振捣混凝土的技术关键所在，由于优质矿物掺合料的&微集料效应&、&火山灰效应&、&滚珠效应&，使其在改善免振捣混凝土工作性，提高免振捣混凝土耐久性方面发挥了不可替代的作用。
