摘要

以辐射松（

Pinus radiata

）大厚度旋切单板胶合板为覆面板、模塑聚苯乙烯泡沫（expanded polystyrene，EPS）为保温芯层，制备承重型木质结构保温板（structural insulated panels，SIPs）。依据覆面板两种厚度（30、60 mm）、芯层是否填充EPS，设计四组足尺SIPs试件，分别进行单调与往复循环加载试验，分析SIPs试件的破坏模式，并测试其极限荷载、抗剪强度、刚度、延性及耗能等关键性能参数。结果表明：1）增加覆面板厚度可提升SIPs的承载力与刚度，在单调加载下，60 mm厚度胶合板覆面SIPs试件的极限荷载是30 mm厚度胶合板覆面SIPs试件的1.88倍（填充EPS）或1.77倍（未填充EPS）；2）EPS填充能有效改善SIPs试件的延性与耗能性能。覆面板厚度为60 mm时，在单调加载下，填充EPS的SIPs试件耗能是未填充EPS试件的2.02倍；在往复循环加载下，填充EPS的SIPs试件耗能是未填充EPS试件的1.67倍；3）EPS促使破坏模式从覆面板螺栓孔局部脆性撕裂向墙骨-覆面板界面、墙骨-底梁板节点等多部位渐进式混合损伤发展，结构整体性增强；4）往复循环加载下SIPs试件的极限承载力普遍低于单调加载结果，并呈现推拉方向的不对称力学特征。研究表明，覆面板厚度是影响SIPs抗侧承载与变形能力的关键性因素，EPS填充则是改善延性与耗能性能的有效途径，二者结合可协同提升承重型SIPs的抗侧性能，为该类构件在中高层建筑等荷载要求较高场合中的应用提供试验支撑与设计参考。

Abstract

Load-bearing structural insulated panels (SIPs) were fabricated using thick plywood made of rotary-peeled from radiata pine (

Pinus radiata

) veneer as the sheathing material and expanded polystyrene (EPS) foam as the insulation core. Four groups of full-scale SIP specimens were designed according to two sheathing material thicknesses

30 and 60 mm

and the presence or absence of EPS core infill. Monotonic and reversed cyclic loading tests were conducted to investigate the failure modes of the SIP specimens and t

o determine key performance parameters

including ultimate load

shear strength

stiffness

ductility

and energy dissipation capacity. The results showed that: 1) increasing the thickness of the sheathing material enhanced the load-bearing capacity and stiffness of the SIPs. Under the monotonic loading

the ultimate load of SIP specimens with 60-mm-thick sheathing material was 1.88 times that of specimens with 30-mm-thick sheathing material when filled with EPS

and 1.77 times that of specimens without EPS infill; 2) EPS infill effectively improved the ductility and energy dissipation capacity of the SIP specimens. Under the monotonic loading

the energy dissipation of the EPS-filled SIP specimens was 2.02 times that of specimens without EPS infill for the 60-mm-thick sheathing material group. Under the reversed cyclic loading

the energy dissipation of the EPS-filled SIP specimens was 1.67 times that of specimens without EPS infill for the 60-mm-thick sheathing material group; 3) EPS changed the failure mode from localized brittle tearing around bolt holes in the sheathing material to progressive mixed damage at multiple locations

including the stud-sheathing material interface and the stud-bottom plate connections

thereby improving the structural integrity; 4) under the reversed cyclic loading

the ultimate load-bearing capacity of the SIP specimens was generally lower than that obtained under monotonic loading

and asymmetric mechanical behavior was observed in the push and pull directions. This study demonstrated that the thickness of the sheathing material was a critical factor affecting the lateral racking performance and deformation capacities of SIPs

while EPS infill was a key measure for improving ductility and energy dissipation capacity. The combined use of increased sheathing material thickness and EPS infill could synergistically enhance the lateral racking performance of SIPs

providing experimental support and design reference for the application of such components in mid- and high-rise buildin

gs and other scenarios with high load-bearing requirements.
