According to the mechanical characteristics of composite reinforced concrete beam and the principle of virtual work, a finite element model and its collapse criterion were put forward to imitate the shear-resistant behavior on the junction surface of composite reinforced concrete beam in this paper. 本文根据混筋混凝土组合梁的受力特点,利用虚功原理,提出了模拟组合梁结合面抗剪性能的有限单元模型及其破坏准则。
Some advanced technology is adopted including deep trench isolation, SIC, self-aligned Si3N4/ SiO2 composite sidewall as Emitter-Base junction isolation and ultra-thin interior base formed by BF2 implantation. 工艺中采用了先进的深槽隔离技术、选择性集电极注入(SIC)技术、使用自对准Si3N4/SiO2复合侧墙作为E-B结的隔离、用低能氟化硼取代硼注入基区形成超薄内基区。
The fractography showed that the composite materials prepared by the hot pressing method took place fracture in the interface junction between matrix and particulate reinforced; and under high pressure sintering, SiC and aluminum matrix composites had a strong combination, most SiC cleavage fracture occurred. 断口分析表明,高压烧结的复合材料中SiC与基体结合较好,SiC大都发生解理断裂;热压烧结的复合材料在SiC增强相与基体界面的结合处发生断裂。
The semi-rigid composite joint with the Beam-Column end-plate connection is actuating junction in the steel frame construction and one of the critical factor for performance of the whole steel frame construction. 梁柱端板连接半刚性组合节点是钢框架结构中连接的传力枢纽,是影响整个钢框架结构性能的关键因素之一。
