［摘要］介紹了整體預應(yīng)力裝配式板柱結(jié)構(gòu)的基本力學原理，針對裝配式結(jié)構(gòu)體系的特點，采用有限元施工階段模擬方法，研究了此類結(jié)構(gòu)考慮裝配施工過程的力學性能，著重研究了以下兩個方面：對考慮裝配施工過程的分析結(jié)果與“等同現(xiàn)澆”結(jié)構(gòu)一次成型的分析結(jié)果進行偏差分析；對裝配施工過程中邊肋與明槽初始變形不協(xié)調(diào)導致的受力不均進行了分析。得出結(jié)論如下：整體預應(yīng)力裝配式板柱結(jié)構(gòu)宜首選采用考慮裝配施工過程的分析方法進行設(shè)計，宜考慮梁端剛域效果；當采用“等同現(xiàn)澆”方法進行分析設(shè)計時，明槽部分的內(nèi)力或配筋應(yīng)按比例調(diào)幅，調(diào)幅之后的內(nèi)力或配筋應(yīng)疊加到邊肋中。

Abstract:The basic mechanical principle of the monolithic prestressed assembled slab-column structure was introduced. Based on the characteristics of the fabricated structural system, the finite element construction stage simulation method was used to study the mechanical properties analysis method of this type structure considering the assembly process. The following two aspects research were focused on:  deviation analysis was carried out on the analysis result of considering the assembly construction process and the analysis result of the one-time forming of the "equivalent cast-in-place" structure;  the uneven force was analyzed caused by the uncoordinated initial deformation of the edge rib and the open groove during assembly construction. The conclusions are as follows:  the monolithic prestressed assembled slab-column structure should be first designed with the analysis method considering the assembly process, the beam end domain should be considered;  when using the "equivalent cast-in-place" method for analysis and design, the internal force or reinforcement of the open groove part should be adjusted in proportion, and the internal force or reinforcement after the amplitude adjustment should be superimposed on the edge rib.

Keywords:assembled by monolithic prestressing; column-slab structure; construction progress
