单项选择题

1～3 某一设有吊车的钢筋混凝土单层厂房，下柱He=11.5m。上、下柱的截面尺寸如题1～3图所示。截面采用对称配筋，as=as’=40mm。采用C30的混凝土，纵向钢筋为HBB335，内力组合后的最不利内力设计值，上柱是M= 112kN·m，N=236kN；下柱是M=400kN·m，N=1200kN。

若已知上柱的偏心距增大系数η=1.12，初始偏心距ei=495mm，则上柱截面按对称配筋计算的一侧纵向钢筋面积与下列（）项数值最为接近。

A．605mm2

B．953mm2

C．724mm2

D．890mm2

单项选择题

During the past years, intelligent technology has evolved (116) three generations. The first was characterized by tools such as prolog and OPS. prolog is a simple backward-chaining environment, and OPS is a simple forward-chaining environment. This led to the second generation of knowledge-engineering environments. Its goal was to model, prototype and construct (117) systems.

All three generations were oriented toward generic (118) and represented generalized implementation environments for the construction of expert systems. knowledge bases and AI applications.Some of the solution-oriented products are also seamlessly integrated with generic knowledge-engineering environments, permitting end users to add (119) rules and objects, as well as predefined knowledge-based logic to address problems in manufacturing simulation.Marketplace orientation is rapidly (120) toward solution-oriented intelligent product environments. the fourth generation represents a new line of thinking and ’ develop-merit by commercial fu-ms. will reduce the cost risk and development time associated with problem solving.

（116）是（）

A.custom

B.knowledge

C.through

D.problemsolving
