ANALISA TRUSS BANGUNAN MENGGUNAKAN SOFTWARE FRAME 3DD

Analisis struktur merupakan menggabungkan bidang mekanika teknik, teknik material dan matematika teknik guna menghitung deformasi struktur, kekuatan internal, tekanan, reaksi tumpuan, percepatan, dan stabilitas. Hasil analisis tersebut akan digunakan untuk memverifikasi kekuatan struktur yang akan maupun yang sudah dibangun. Dengan demikian analisis struktur merupakan bagian penting dari desain rekayasa struktur.

Truss terdiri dari ikatan elemen balok tegangan tarik dan elemen kolom pendek dan biasanya berbentuk segitiga. Truss bidang disusun dari elemen-elemen yang berada pada bidang yang sama (2 matra) dan seringkali digunakan untuk jembatan-jembatan, penopang atap. Sebaliknya, truss ruang memiliki elemen-elemen yang dapat mengembang ke dalam tiga matra dan cocok untuk derek dan menara.
