Lane’s weighted creep theory assumes A. Equal weightage to horizontal and vertical creeps B. Double weightage to horizontal creep and one weightage to vertical creep C. Triple weightage to horizontal creep and one weightage to vertical creep D. Triple weightage to vertical creep and one weightage to horizontal creep

The correct answer is: A. Equal weightage to horizontal and vertical creeps.

Lane’s weighted creep theory is a method of estimating the long-term creep deformation of concrete structures. It assumes that the creep deformation is proportional to the applied stress, and that the creep deformation in the horizontal and vertical directions are equal.

Option B is incorrect because it assumes that the horizontal creep deformation is twice as large as the vertical creep deformation. This is not a realistic assumption, as the creep deformation in the two directions is typically very similar.

Option C is incorrect because it assumes that the horizontal creep deformation is three times as large as the vertical creep deformation. This is an even less realistic assumption than Option B, as the creep deformation in the two directions is typically

Option D is incorrect because it assumes that the vertical creep deformation is three times as large as the horizontal creep deformation. This is the opposite of the realistic assumption, as the creep deformation in the two directions is typically very similar.
