As a result, it was found that the main reason for the increase in creep and reduction of its reversibility for aerated concrete, taking into account its carbonization factor, is the fact that the content of the gel-like part of silica acid increases and the volume of the crystalline part ...
14.Analysis on Concrete Creep Effects during the Cantilever Construction of Continuous Rigid Frame Bridges连续刚构桥悬臂施工过程中混凝土徐变效应分析 15.Structure Analysis and Program Design of Construction Process Simulation with Considering Creep Effects考虑徐变效应的施工过程模拟结构分析与程序设计 16.UNCERTAI...
Since the temperature effect of the steel beam and the creep effect of the CFRP cloth have been given in38, only the creep effect of the concrete is considered herein, that is, only the interface force between the concrete slab and the steel beam is considered. Several assumptions are made...
1.Thecreep resistanceof the alloy increases with the number of second phase precipitates (such as carbide particles and a precipitation) uniformly distribu.结果表明:位错环组是合金蠕变变形结构中的典型位错组态;合金的蠕变抗力随β基体上弥散分布的第二相析出数量的增加而提高。 2.The results show that th...
Xin Lu and Zhu Wan-xu15found that after adding a middle pressure bearing step to the anchor plate, the angle between the strut-and-tie model in the anchorage zone increases, and the uplift capacity improves. Three concrete specimens were poured for force transfer testing in the anchorage ...
5)Prestress loss in a prestressed concrete structure is due to concrete creep. 6) Concrete members will be subjected to loads as great as the design loads at an early age as a result of quick construction practices; this can result in deflections owing to cracking and low elastic modulus at...
Lifestyle creep happens when you increase spending in tandem with your income, which could prevent you from accomplishing your financial goals.
Mechanical properties and energy evolution of drilling shaft lining concrete under hydro-mechanical coupling 2024, Construction and Building Materials Citation Excerpt : In these areas, most shafts traverse through water-bearing soft rock strata of the Cretaceous and Jurassic periods, characterized by high...
First, the creep process of the marine clay-concrete interface can be largely decomposed into the instantaneous creep stage, the attenuation creep stage and the uniform creep stage. Second, the creep stability time and the shear creep displacement generally increase as the shear stress level ...
(Atkinson1982; Lajtai et al.1987; Aubertin et al.2000; Brantut et al.2013; Aydan et al.2015). In general, an idealized creep deformation includes three distinct regions: (a) primary phase or transient creep where the creep strain increases with a decrease in the rate, (b) secondary ...
