| 摘 要： | 文章着重介绍当在钢屋架上增设检修电葫芦,且荷载作用点不在屋架节点时,屋架杆件的内力变化,以及易被忽略的电葫芦水平惯性力对杆件内力的影响。为实际工程设计、改造有悬挂移动荷载的钢屋架选型及应用提供参考。 |
| 关 键 词： | 钢屋架 电葫芦 水平惯性力 |

| Abstract: | The thesis introduced when adding maintenance electric hoist on steel roof truss, when load point was out of the roof truss node, roof truss rods of the internal force of change, electric hoist horizontal inertial force that being easily ignored influencing member internal force. The technology provided the reference for practical engineering design, the transformation suspended the steel roof truss type selection and application of moving load. |
| Keywords: | steel rooftruss electric hoist the level ofinertial force |
