l-hb 解釋

First of all, the paper carried out test study on four two - spanned model members of fsmrcwb, including three 1 / 2 - scaled two - storeyed models and one 1 / 3 - scaled three - storeyed model. the study considered such factors as span ratio - l1 / l2, height - span ratio - hb / l of the beam, and cavity etc. the paper analyzed the test results, including analysis on mechanical property of the composite wall beam under vertical loads, and failure mode, deformation capacity, aseismic performance under horizontal loads and constant vertical loads

首先，進行了三個兩跨兩層和一個兩跨三層的框支密肋復合墻梁的模型試件試驗研究，主要內容包括：框支密肋復合墻梁在豎向荷載作用下的受力性能，在豎向荷載與水平低周反復荷載共同作用下的受力性能、變形性能、滯回性能和破壞形態，並將框支密肋復合墻梁試驗與框支砌體墻梁試驗進行對比分析。
