摘要

摘要本实验研究展示了山墙钢筋混凝土梁在多个开口（6个和8个）和立柱倾斜情况下的性能，旨在找出这种类型梁的强度降低情况。发现的主要结果是：对于在类似梁长度上延伸的开口，最好增加支柱（开口）的数量，即增加开口数量会导致开口面积减少，这使我们能够传递应力，并在上弦杆和下弦杆之间充当杠杆臂。此外，研究结果表明，相对于垂直立柱，倾斜立柱在中点处具有更大的载荷。对于具有6个和8个开口的竖柱山墙，极限强度分别降低了31.5%和25.6%，而具有斜柱的山墙则分别降低了29%和17.3%。

Performance of reinforced concrete non-prismatic beams having multiple openings configurations

Abstract This experimental study demonstrates the gable-reinforced concrete beams’ behavior with several number of openings (six and eight) and posts’ inclination, aimed to find the strength reduction in this type of beam. The major results found are: for the openings extending over similar beam length it is better to increase the number of posts (openings), i.e., increasing opening number led to decrease in opening area, which allows us to transmit stresses and act as lever arms between the upper and the lower chords. Also, findings revealed that the inclined posts have larger loading at the mid-point relative to vertical ones. For gables with vertical posts having six and eight openings, the ultimate strength reduction was 31.5 and 25.6%, whereas it was 29 and 17.3% for those with inclined posts, respectively.

期刊介绍： The journal focuses on the micromechanics and nanomechanics of materials, the relationship between structure and mechanical properties, material instabilities and fracture, as well as size effects and length/time scale transitions. Articles on cutting edge theory, simulations and experiments – used as tools for revealing novel material properties and designing new devices for structural, thermo-chemo-mechanical, and opto-electro-mechanical applications – are encouraged. Synthesis/processing and related traditional mechanics/materials science themes are not within the scope of JMBM. The Editorial Board also organizes topical issues on emerging areas by invitation. Topics Metals and Alloys Ceramics and Glasses Soils and Geomaterials Concrete and Cementitious Materials Polymers and Composites Wood and Paper Elastomers and Biomaterials Liquid Crystals and Suspensions Electromagnetic and Optoelectronic Materials High-energy Density Storage Materials Monument Restoration and Cultural Heritage Preservation Materials Nanomaterials Complex and Emerging Materials.
