Introduction The maximum historical effective stress of soil is referred to pre-consolidation pressure and determines the changes of stress during the formation of soil.1 Due to the difference of geological effect and the stress changes, the process of consolidation may differ during the formation and current process. According to the definition of pre-consolidation pressure, when the external load is lower than the pre-consolidation pressure, the natural soil only has a tiny deforma...

 预固结压力的计算与超固结土的强度和变形参数有关，反映了土体的应力路径和变形特征。因此，准确、方便地计算预固结压力在传统土力学中具有重要意义。本文利用MATLAB工具箱，采用基于BP神经网络的方法对预固结压力进行计算和建模。最后，精度和效果

Introduction There is a consensus among researchers that the aggregate shape properties affect performance, but a debate has arisen over the ability of the tests to quantify the related shape properties. In compacted mixtures, angular-shaped particles exhibit greater interlock and internal friction, and, hence, result in greater mechanical stability than do rounded particles (Little, Button et al, 2003). Thus, angular and rough-textured aggregates are crucial to develop interlocking among agg...

 集料的物理性能直接关系到路面的性能。刚度、疲劳响应、抗剪强度和永久变形是骨料形态、纹理和棱角等影响的一些病害。角质度是骨料形状的重要性质，角质度越大，颗粒间的互锁性越好，内摩擦和力学稳定性越好，因此路面抗压性能越好。一场辩论已经兴起 让大学校园适合肢体和运动残障人士(案例研究:德黑兰大学美术学院) //www.a-i-l-s-a.com/vol11noSpecial/making-university-campuses-suitable-for-the-physical-and-motor-disabled-people-case-study-college-of-fine-arts-university-of-tehran/ 2016-08-31 2018-12-01 晨祷,卡塔洋 第11卷第1期特刊(2016年)

Introduction One of the principles accepted by the philosophers is the principle of movement. They believe that the world is thoroughly in the course of movement and movement in human includes gradual change and development of any creature to improve the forces stored in it to excellence. Therefore, necessary facilities for evolution and improvement should be available for all classes of the society. Disabled people are not an exclusion to this rule. Their existence among other classes of the...

 任何社会的发展和繁荣在很大程度上取决于福利设施的供应和提供合适的空间来使用它们。These facilities assist in the grounds for social growth only if their scope covers all individuals of the society with special needs. Since a major part of any society is constituted by the aged, disabled, impaired and disabled people, failure to pay attention to that class not only may result in their lack of motivation and deprivation of society fro

Introduction Geodesic dome is a space type of structure that looks like a section of a ball or sphere. This instrument is made of a grid of triangles that eventually form a spherical surface. The greater the number of triangles the better form of a sphere-shaped dome is approached. (Urner, 2016) The using hardness and stability of triangle will cause the strength of dome and integration of the parts spreads the force in all the sphere so finally the geodesic dome makes an efficient structure....

Introduction The issue of steel structures fireproof is one of the issues highly considered globally during the recent years. Considering firefighting and Tehran Municipality instructions on compulsion of making steel structures fireproof, cementitious materials is one of the materials accepted in Iran to fulfill this issue.1 Firecut-F1 cement based fireproof substance which is used exclusively by Beta Engineering Group in Iran is one of these materials. Two important discussions of ...

考虑到结构钢在550-550℃的一定温度范围内，其热阻损失一半，因此，根据UL 263和ASTM-E119国际标准，需要对所有截面进行喷涂防火物质的厚度，以加强结构。然而，根据伊朗使用的结构使用这些标准受到工程师们的各种意见的影响，这里已经尝试过，这些关系的某一部分是成比例的 为建筑的特定功能选择合适的新结构 //www.a-i-l-s-a.com/vol11noSpecial/appropriate-new-structure-selection-for-a-specific-function-of-architecture/ 2016-08-31 2018-11-27 Maryam Ghorbanzadeh 第11卷第1期特刊(2016年)

Introduction To achieve the necessary harmony between architectural design and its construction requires analysis of a variety of structures and choosing the most appropriate one for each function. Due to extensive requirements and the need to improve the quality of building as is common in most large countries the best industrial production methods and the most use of new structures should be considered. So that our architecture in Iran needs to change from traditional methods to modern m...
