Abstract This paper presents a numerical analysis of the mechanical behavior of structural masonry panels submitted to horizontal and vertical stresses. To evaluate the design process of these structures, the results obtained by the computer simulations were compared with the results determined by the design criteria of ABNT NBR 15961-1 (2011), ACI TMS 530 (2013) and EN 1996-1-1 (2005). The finite element software DIANA v.9.3 was used to simulate two-dimensional models with the simplified micro modelling procedure. The results obtained by the normative standards were more conservative than the results of the numerical model, as expected. With the increase of the pre-compression level, the computer simulation has demonstrated the increasing trend of the values of resistant forces, besides the change of the way of rupture of the panels. Among the three standards evaluated, the American Standard was the most conservative.

Dendrocalamus Asper

Bambu Petung (Dendrocalamus asper) dengan sifat mekanik yang dapat disejajarkan dengan kayu masih sangat rentan terserang organisme perusak. Penelitian ini bertujuan untuk mengetahui sifat fisik, sifat mekaniknya, pola kerusakan bambu laminasi Petung pasca pengujian mekanik serta metode pengawetan yang efektif terkait dengan retensi pengawet. Penelitian mengacu pada Standar Nasional Indonesia dan American Standard Testing and Material dengan menguji retensi bahan pengawet, sifat fisik (kadar  air dan kerapatan) serta sifat mekanik bambu laminasi (keteguhan geser perekat dan uji lentur) hingga benda uji mencapai pembebanan maksimum (failure). Hasil uji kemudian dibandingkan antara bambu sebelum dan setelah diawetkan yang kemudian dianalisis secara statistik. Hasil penelitian menunjukkan bahwa pola kerusakan balok bambu laminasi cenderung mengalami kerusakan geser horizontal pada garis rekatnya (delaminasi). Hasil analisis statistik menunjukkan bahwa perlakuan pengawetan memiliki pengaruh yang tidak signifikan terhadap Penurunan keteguhan geser perekat.
