7、中还参考了《施工技术》2002（3）：《扣件式钢管模板高支撑架设计和使用安全》中的部分内容。二、工程概况本工程为郑州凯通高科技产业园产品展示销售中心及2#研发楼工程，位于郑州市经济技术开发区。工程总占地面积16159m2，建筑总面积26055.37m2，基础采用柱下独立基础和条形基础，主体为钢筋混凝土框架结构。该工程主要功能为产品展示和办公等。其中地下室为停车场及设备用房，Ⅰ、Ⅱ区产品展示销售中心为地下一层地上四层，建筑高度19.8m。Ⅲ区2#研发楼为地下一层地上六层，建筑高度为23.7m。本工程设计使用年限为50年，抗震设防烈度为7度，耐火等级地下部

8、分为一级，地上部分为二级。本工程产品展销中心Ⅰ区～轴四层和屋面楼板结构中，每层各有6榀预应力大
