    Cho em hỏi, kết quả bài toán Inplace có phần chuyển vị nút, vậy trong tính toán mình có một cái giá trị tới hạn nào để biết chuyển vị đó chấp nhận đươc hay không?

    1/In general, the allowable deflection of L/240 (where L is span length) has been set as a basis of design. For cantilever beam, the allowable deflection of L/180 is used.
    2/
    The maximum vertical joint displacements are checked for joints.
    The allowable relative deflection is L/200 or L/150 depending on the load out condition as indicate follow:
    Allowable limit = The allowable vertical deflection at a point in a member under operating loads.
    Allowable limit = L/200 used for simply supported beam
    Allowable limit = L/150 used for cantilever beam
